[펌] [Tip] JSONP를 이용하여 Cross Domain 해결

반응형
출처 : http://warmz.tistory.com/739

Ajax 로 다른 도메인에 있는 url 을 호출해 데이터나 HTML을 가져오는건 보안상 안된다고 한다. 되면 참 좋을텐데;;

뭐 아무튼 이걸 해결하기 위한 방법으로 JSONP 라는 형식으로 호출하던가 아니면 Proxy Servlet 을 하나 맹글어 그 서블릿을 거쳐 HttpClient 로 가져오는 방법, 훌래쉬를 이용하는 방법이 있다고 한다.!

그중에서 이번엔 JSONP 형식으로 호출하는 방법을 연구해 보겠다.

JSONP 형식이란 뭐 별건 아닌것 같고 기존에 서버에서 리턴해 주던 

{"key1" : "value1",  "key2" : "value2"} 요런 json 문자열을 

callback({"key1" : "value1",  "key2" : "value2"}); 요런식으로 임의의 함수를 호출해 주는 형식의 문자열로 리턴해 주는것을 말하는것 같다.

즉, jsonp 로 ajax 호출을 하기 위해선 아무 url 이나 안되고  callback({"key1" : "value1",  "key2" : "value2"});  요런식으로 함수안에 json 문자열이 들어간 형식으로 서버에서 리턴을 해줘야 가능하다.

각설하고 jQuery를 활용해 맹글어 보자.

$.getJSON("http://127.0.0.1:8080/server/data.jsp?callback=?", function(d){

    dataType : "jsonp",
    jsonp : "callback",
    success : function(d){
        // d.key;
    }
});

방법#1 이나 방법#2는 작동하는게 동일하다. 취향에 맞게 쓰임새에 맞게 쓰면된다. 개인적으로 방법#2 를 여러가지 원하는 ajax 호출 옵션을 줄수 있어서 더 좋아한다.

살짝 설명해 보면 방법#2 에서 쓴 ajax 옵션중 jsonp는 데이터를 넘겨줄 서버에서 받는 callback 함수명 파라메터이다. 서버에 따라 원하는 callback 함수명을 적어줘야 한다. 방법#1을 보면 대충 이해할 수 있다.

jsonp 옵션에다 적어준 함수명은 ajax 호출 url 뒤에다 방법#1에서 처럼 파라메터 형식으로 자동 추가된다.

Overview

Introduction

MeadCo's ScriptX is a suite of ActiveX technology components designed to provide absolute control over document printing operations from client and server computers running the Microsoft Windows Web Browsing Platform.

Part of its purpose is to ensure the consistent formatting and appearance of printed output from any local or networked printer, regardless of the printing attributes already set in that computer's Internet Explorer (IE) browser. ScriptX applies a document author's desired attributes at the time of printing browser window or framed content, but thereafter automatically restores all default settings and makes no permanent changes.

ScriptX 1.0 was introduced by MeadCo in 1998 as a freely distributable utility offering a limited set of print formatting functionality - the scripted control of the printing of HTML frame or window content (with or without a prompt), and the specification by script of printing parameters such as page headers, footers, marginsand paper orientation within IE.

That basic functionality is still available at no charge and is freely distributable. Features that are part of that 'free' printing subset are marked in this document asbasic.

With the releases of later versions, significantly more advanced printing functionality was introduced which is only accessible in the presence of a paid-for MeadCopublishing license.

Target platform

ScriptX has been tested on and supports Microsoft Windows Web Browsing Platform versions 4.01 SP1 - 7.0 on all Microsoft Windows Win32 OS platforms (including Vista).

ScriptX v6.4 and later no longer support Windows 9x/NT. For maintenance support of these operating systems, please see ScriptX win9xNT/NT Maintainance Mode Binaries.

ScriptX v6.4 and later are supported on all Microsoft Windows client and server platforms from Windows 2000 onwards with Internet Explorer 5.5 or later.

Product credits

ScriptX has been widely adopted and acknowledged by the Web and intranet development communities. Check out:

Summary of examples

    Basic
    Illustrates the straightforward use of the freely distributable ScriptX basic printing functionality: headers, footers, margins and paper orientation.

    Advanced
    Illustrates the typical use of ScriptX advanced printing functionality for which a publishing license is required.

    Techie
    An all-in-one technical example illustrating the most advanced use of licensed ScriptX functionality.
    Printing reports and customised documents
    Provides a discussion of printing customised documents and reports with ScriptX and a number of samples of differing techniques. A download of all the sample code is included.
    Direct printing

Feel free to investigate the source code from any of the examples and to cut & paste fragments into your own applications.

Advanced control of HTML Printing with ScriptX

Advanced printing functionality can only be used with a paid-for publishing license. Some of the advanced features enabled with a license are:

  • Control over the printing of a document's background color and images (printBackground).

  • A SetMarginMeasure method to ensure that the chosen unit of measure for margins (inches or millimeters) will be consistent across machines with different locale settings.

  • Facilities to select a non-default printer, paper size & source, page range & collation and number of copies to print.

  • Reliability and scalability. The PrintHTML(url) method can queue and print any number of documents without compromising system performance. This is especially important for server side printing. On the client side, PrintHTML works in the HTTP session context of the calling page (SSL is supported as well).

  • Precise tracking of spooler activity (IsSpooling, WaitForSpoolingComplete, onafterprint). By default, when the Internet Explorer window is closed or the page navigated away from whilst a print-out is still being spooled, the user will be prompted. The prompt can be customized or disabled (onbeforeunload).

  • Print settings changes (headersbasic, footersbasic, marginsbasic, paper orientationbasic, printer name, paper size, paper source, page range selection, number of copies, collation, duplex mode) once made from script now become active for Internet Explorer's native UI Print... and Page Setup... commands, as well as for the native window.print() script method, during the time that the document is displayed. Now an author doesn't need to put a [Print] button on an HTML page.

  • Internet Explorer's native printing UI can be trapped and cancelled, or handled in a particular way (disableUI, onuserprint, onuserpreview, onuserpagesetup). A document's DHTML user interface can also be updated in response to user changes in the Page Setup and Print dialogs (onpagesetup). See the Techie printing example for an illustration of UI handling.

  • All changes made to print settings affect only the current document (in the current tab) when it is printed or previewed. Settings are untouched in other IE windows or tabs and will not apply to any other documents viewed in the current window/tab.

  • A redirect of print data can be made to a specified file name (printToFileName).

  • Basic printing of Microsoft Officetm documents.

  • Printing of PDF documents (PrintPDF and BatchPrintPDF).

Backwards compatibility

All releases of ScriptX are fully backwards compatible with previous releases and for advanced functionality will work with all existing publishing licenses. ScriptX works in close concert with the Microsoft Windows Web Browsing Platform and as a result  is updated to work with all latest releases and patches. All code updates are free; there is never a charge for obtaining the latest code.

We strongly recommend that you update your <OBJECT> elements to reference the current version 7,0,0,8 and update smsx.cab on your servers.

  • An important compatibility issue is that ScriptX printing will always prompt when called in the context of Internet Explorer's Internet Security Zone (check the zone icon in the browser's status bar). This is done to prevent anonymous Internet content invoking printing without a prompt (see PRB: Printing with WebBrowser from Internet Explorer Raises Print Dialog Box in Internet Explorer 5).

    For the My Computer, Local Intranet and Trusted Sites Security Zones promptless printing will work. If you need promptless printing for the Internet Security Zone, you should obtain a publishing license that will bind the deployment of ScriptX to the URL addresses from which you want to serve ScriptX-enabled content.

  • Another important note concerns margin units of measure (inches and millimeters). By default ScriptX uses the units of measure set on the client machine. This is OK when pages are being authored for a known environment such as a small corporate intranet where all Regional Settings are identical, but in a broader environment users' Number settings are certain to vary. So an author should specify the SetMarginMeasure method with a value of either 1 (mm) or 2 (inches). ScriptX will then print to the margins specified regardless of -- and without affecting -- a user's default Regional Number Settings.

What's New Summary

A full listing of the release of ScriptX versions and the modifications they contained is available on the ScriptX History page.

v6.2

Version 6.2 introduces the printerControl, Jobs and Job objects to provide detailed information about the available printers and control of the print queue for a printer. The use of methods that control the print queue requires that the user has administrator rights on the printer.

Also included in this version is an extension of the MeadCo licensing scheme to provide a usable distribution model and allow the use of ScriptX within desktop applications.

v6.3

Version 6.3 provides support for Internet Explorer 7 on Windows XP and Windows Vista; v6.3 is required on the IE 7 platform ... previous versions of ScriptX arenot compatible.

This release includes a new print template that provides the same functionality as that within Internet Explorer 7 - scale to fit printing by default and enhanced print preview with draggable margins and switchable headers. This template is available for all versions of Internet Explorer from v5.5 so, whilst your users may be running anything from IE 5.5 onwards, you can give them all a consistent print experience.

The use of the new template is optional - by default ScriptX will use the default template for the platform (IE5.5 style on IE 5.5/IE 6 and IE 7 style on IE7. The particular template required can be specified in script using the templateUrl property or may be specified as a parameter to the ScriptX object.

Frames can now be previewed. This was a MaxiPT only feature but is now also included in the Advanced licensed feature set for ScriptX.

A code review has been undertaken with this release, with APIs checked for behaviour and consistency. This has resulted in some cases where in previous releases a property/method would not report an error when an error occurred - errors are now reported. This may necessitate changes to script code if it was assumed that code would run without error.

v6.3.435

From the first build of this version onwards, ScriptX comes in a single signed CAB - smsx.cab. In addition to fixes for a number of issues, this release introduces improvements for application licenses and the ability to install license updates without requesting permission from the user (this will only occur for updates of an already accepted license).

Two new methods are introduced to provide additional control over the behaviour of the new IE 7 style template. These methods require a publishing license:

  • SetPreviewZoom -  provides control over the zoom factor used on print preview.
  • SetPrintScale -  provides control over the scaling used when printing.

v6.3.436

Version 6,3,436 introduces the ability to send raw text to an attached printer. The text is not rendered to the printer, it is interpreted by the printer. This is useful in scenarios such as controlling a thermal label printer. For more information, see rawPrinting.

v6.4

ScriptX v6.4 and later no longer support Windows 9x/NT. For maintenance support of these operating systems, please see ScriptX win9xNT/NT Maintainance Mode Binaries.

This release also introduces Enterprise+ licensing and preliminary support for IE8. Please note that this release has been tested against IE 8 Beta 1 only, there are no known problems other than under Vista where there are a number of small issues which will be addressed in future releases of IE/ScriptX.

v6.5

ScriptX v6.5 and later fully supports IE8 on all supported platforms (Windows 2000 and later). ScriptX 6.5 is a required upgrade for correct operation with IE8.

In support of IE8 one new property has been added: headerFooterFont. Note that scale to fit and print background colours functionality was already included with ScriptX.

A number of problems have also been resolved, including an issue with the SetPageRange() method. Our documentation has been updated to better describe its behaviour. A development history - as well as latest test version of ScriptX - is available on the ScriptX beta page.

v6.6

ScriptX v6.6 introduces a 64-bit Edition for x64 systems and controlled printing of PDF documents with the licensed Corporate 32-bit Edition of ScriptX. ScriptX v6.6 also includes support for Internet Explorer 9 Beta 1 and IE 9 Preview up to Preview 7.

ScriptX 6.6 is a required upgrade for correct operation with IE9.

How do I use the ScriptX object?

Before reading further, please have a look at our illustrative Basic, Advanced and Techie examples of ScriptX printing to get an idea of what ScriptX can do for you.

There are three scenarios in which ScriptX provides the solution for printing of HTML documents with the Microsoft Windows Web Browsing Platform:

  1. Within the Internet Explorer browser, on client-side HTML or XML pages. Here, ScriptX provides full scripted control of the printing experience within IE, allowing choosing the output printer, orientation, page header and footers etc and the initiation of the print. ScriptX is ideal for deployment within web applications hosted within Internet Explorer.
  2. On the server, where ScriptX performs as part of server side request processing, printing an html document loaded from the same or different server.
  3. As part of a desktop application, ScriptX can be used to print HTML documents from the file system, a web server or generated as an 'inline' string.

Note that the use of ScriptX on the server always requires a license. All licenses are available (on request to feedback@meadroid.com) for a trial period to enable full and proper evaluation of the suitability of ScriptX for a particular usage.

Client-side deployment within Internet Explorer (x86 32-Bit Edition).

Typically ScriptX is deployed as a client-side ActiveX control, instantiated and scripted on an HTML or XML page as an <OBJECT> element. Download and installation is a one-time client-side event and is handled automatically by the standard Internet Explorer Component Download technology.

Requirements for a successful installation

  • The end user's system must have the "Download Signed ActiveX Controls" and "Script ActiveX control marked as safe for scripting" security settings enabled for the corresponding Security Zone. These are the default settings for the My Computer, Local Intranet, Trusted Sites and Internet Security Zones.
  • In addition, on Windows 2000 systems and later, the user must be logged on as an Administrator/Power User with the ability to write to the HKEY_LOCAL_MACHINE registry hive and the Windows system folder (typically c:\windows\system32). For Windows Vista and later, the user must be able to complete an Account Control elevation dialog, either through accepting the dialog since they are logged in as an administrator or by entering the user name and password of a suitable administrators account.

Alternative installers (and 64-bit Edition of ScriptX)

If the above requirements cannot be met we suggest that you ask to review our Corporate Resource Kit, a $500-per-year cost-option for licensees which comes as a collection of .msi and merge modules and documentation. The Corporate Kit enables more modern and flexible installation choices than can be provided from our historic .cab-based schema, including the ability to develop a custom installer to requirement using the supplied merge modules.

In addition, the Corporate Resource kit includes the 64 bit Edition of ScriptX. Whilst primarily intended for deployment on server systems for server side printing, the 64 bit Edition can be deployed for use with the 64 bit Edition of Internet Explorer. Please note that, at the time of writing, the default edition of Internet Explorer is 32 bit on all Microsoft Windows operating systems, including 64 bit OSs.

Codebase referencing and use of the object

From the first 6,3,435,x version onwards, ScriptX comes as standard in a single signed CAB - smsx.cab - which is part of a download package obtainable from theScriptX site. The CAB file should be placed on the web server and its location should be referenced by the CODEBASE attribute of the <OBJECT> tag, as shown below.

NOTE: In your own code, we recommend that you place the ScriptX <OBJECT> elements in the document's <BODY> container.

  • Make sure that you provide the correct relative or fully-qualified path to the CAB file and the correct version info (7,0,0,8) in your CODEBASE attributes.

  • Start to script the ScriptX object only when the page is fully loaded i.e. once the window.onload event has occured.

  • Use the defer attribute where appropriate in your scripts: <SCRIPT defer>...<SCRIPT> and avoid immediate script statements (i.e. code which is outside of any function scope). This is an under-appreciated but very useful feature which instructs the script to execute only when the whole document's DHTML content is completely parsed. This way you can be sure of accessing every element on the page.

  • The 'de-facto' standard, started by this documentation is to use the id 'factory' for the ScriptX object. Any id that is desired may be used.

  • For simplicity, these documents directly refer to the object via its id rather than using document.getElementById(). Either approach is acceptable; if the samples are inspected via View Source it will be seen that the jQuery library is used in the samples, along with a wrapper class to safely access the ScriptX object. The use of jQuery etc is also entirely optional.

The following code snippets assumes that smsx.cab exists in the same folder as the hosting page itself.

Basic functionality:

<object id="factory" viewastext style="display:none"
classid="clsid:1663ed61-23eb-11d2-b92f-008048fdd814"
  codebase="smsx.cab#Version=7,0,0,8">
</object>

The Basic printing example illustrates the use of the basic printing subset.

The viewastext attribute prevents an authoring tool such as Microsoft FrontPagetm or Visual InterDevtm from running the object at design time. This attribute is not required if you do not use these tools and note that it can cause problems in some environments; for example strict xhtml documents.

NOTE: with the 'basic' subset, you can only script header, footer, page margins, paper orientation, Print and PageSetup methods and properties.

Specifying a template (e.g. IE 7)

With version 6.3 and later, you may specify the template to use; this is particularly useful when wishing to provide the Internet Explorer style template (default scaled to fit printing) to users with IE 5.5/6.0 browsers or when specifying the use of the MaxiPT template.

<object id="factory" viewastext style="display:none"
classid="clsid:1663ed61-23eb-11d2-b92f-008048fdd814"
  codebase="smsx.cab#Version=7,0,0,8">
	<param name="template" value="MeadCo://IE7" />
</object>

The ability to specify a particular in-built template is included in the 'basic' subset.

Advanced functionality:

<!-- MeadCo Security Manager -->
<object viewastext style="display:none"
  classid="clsid:5445be81-b796-11d2-b931-002018654e2e"
  codebase="smsx.cab#Version=7,0,0,8">
  <param name="GUID" value="{0ADB2135-6917-470B-B615-330DB4AE3701}">
  <param name="Path" value="sxlic.mlf">
  <param name="Revision" value="0">
</object>

<!-- MeadCo ScriptX -->
<object id=factory viewastext style="display:none"
classid="clsid:1663ed61-23eb-11d2-b92f-008048fdd814">
</object>

NOTE: the {0ADB2135-6917-470B-B615-330DB4AE3701} value of the GUID parameter used above identifies the MeadCo evaluation license that authors may use to experiment with Advanced printing capabilities. The license validates local filesystem (file://) and local website (http://localhost/) content for evaluation purposes only on a single development computer.

The evaluation license is periodic. It will expire in a few months and will be replaced by a new one with a different GUID, so any code depending on the evaluation license may suddenly stop working at any time.

Registered customers are issued with an unique license identifier and a digitally signed sxlic.mlf license file. See the licensing page for more details.

Check out the sources of the Advanced and Techie printing examples for a complete illustration of how to use licensed ScriptX functionality. The following JScript code snippet shows how to modify printing settings so as to print to a specific printer:

<script defer>
function SetPrintSettings() {
  // -- advanced features
  factory.printing.SetMarginMeasure(2); // measure margins in inches
  factory.printing.printer = "HP DeskJet 870C";
  factory.printing.paperSize = "A4";
  factory.printing.paperSource = "Manual feed";
  factory.printing.collate = true;
  factory.printing.copies = 2;
  factory.printing.SetPageRange(false, 1, 3); // need pages from 1 to 3

  // -- basic features
  factory.printing.header = "This is MeadCo";
  factory.printing.footer = "Advanced Printing by ScriptX";
  factory.printing.portrait = false;
  factory.printing.leftMargin = 1.0;
  factory.printing.topMargin = 1.0;
  factory.printing.rightMargin = 1.0;
  factory.printing.bottomMargin = 1.0;
}

function Print(frame) {
  factory.printing.Print(true, frame) // print with prompt
}
</script>

A subtle JScript syntax issue may occur when setting a printer name that contains back slashes. Don't forget to double the slashes:

factory.printing.printer = "\\\\FS-LYS-01\\HP5n-759" // print to \\FS-LYS-01\HP5n-759

How to check whether or not the object is properly installed

Upon the window.onload event, test whether or not the object property of the ScriptX or the Security Manager object returns as a valid object. The way to do that is shown in the script snippet below.

In the event that you experience any problems with automatic client-side download and installation, check out HOWTO: Find More Information About Why Code Download Failed and Description of Internet Explorer Security Zones Registry Entries as part of your troubleshooting.

Testing your print-outs

The development and testing of code to produce good-looking printed reports usually takes a number of iterations. To save toner, paper, trees and our own precious time :-) we regularly use the FinePrinttm application from FinePrint Software.

FinePrinttm installs a virtual printer driver that serves as indirection layer between the printing application (Internet Explorer in our case) and a physical or networked printer. In 'bypass' mode it lets us accurately preview and repaginate ScriptX-enabled content before it is actually printed or discarded.

It's also a very handy testing device with which to diagnose printing problems. So because we are physically unable to test ScriptX with every model and version of printer and printer driver that exists in the world, we would greatly appreciate it if you would try printing to the FinePrint driver before reporting errors against ScriptX from your particular printing environment.

Working with Visual Studio and ASP.NET

The samples on this site are implemented using ASP.NET and the MVC extensions. The samples system is used in various locations, including the Infopages where the latest release, hotfixes and development versions of ScriptX may be obtained. The samples system itself provides a compreshensive set of demonstrations of the capabilities and working of ScriptX under all document types and modes.

When working with ASP.NET we recommend creating a server-side control or for MVC a partial view that will outout the various object tags required by ScriptX. We recommend values such as codebase location and version are obtained from AppSettings stored in web.config.

Please note that when working with ASP.NET Forms we recommend that the ScritpX objects are placed outside the <form /> element.

Technical support

Licensees of ScriptX' advanced printing functionality are entitled to unlimited direct-to-company email support and access to new versions of the ScriptX software as-and-when issued, both at no additional charge.

factory

Description

Represents the ScriptX object itself on an HTML page for scripting by its id . For historical reasons, we name it factory.

For WSH or ASP (i.e. server-side) use only, create a ScriptX instance dynamically with the JScript new ActiveXObject횂쨩 or the VBScript CreateObject횂쨩.

Note that you can not use CreateObject or new ActiveXObject to call ScriptX client-side. You should call ScriptX in all client-side cases by the id of the on-page ScriptX object.

See How do I use the ScriptX object for deployment details.

Examples

HTML page:

<object id=factory viewastext style="display:none"
classid="clsid:1663ed61-23eb-11d2-b92f-008048fdd814"
codebase="smsx.cab#Version=7,0,0,8">
</object>

WSH script (JScript):

var factory = new ActiveXObject("ScriptX.Factory")
factory.printing.PrintHTML("http://msdn.microsoft.com/workshop/author/script/dhtmlprint.asp")

ASP page (VBScript):

<%
 set factory = CreateObject("ScriptX.Factory")
 factory.printing.PrintHTML "http://localhost/orders/order.asp?number=" & Request.Form("number")
 set factory = nothing

rawPrinting (v6.3.436 and later)

Description

Represents the direct printing from within Internet Explorer functionality of ScriptX. Version 6.3.436 or later of ScriptX is required.

Note: Direct printing is a cost-option which can be enabled on a 'standard' client-side license for an additional fee of $500.

Direct printing allows for printing to programmable devices such as thermal label printers, whereby a label string can be sent directly to the printer. The Internet Explorer print engine is not used and takes no part in the process. The functionality available from rawPrinting is completely separate from that available from the printing object, and for this reason settings such as printer, paper size, orientation, etc. that may have been set on the printing object for Internet Explorer do not apply to the rawPrinting object.

NOTE: rawPrinting is not supported in any form of usage outside of Internet Explorer.

bottomMarginbasic

Description

Specifies the bottom margin height for HTML print-outs. Cannot be set to be less than the printer's physically unprintable area (unprintableBottom), in which case it will be automatically corrected to the minimum allowed value. If top and bottom margins are set to overlap, they will be corrected to an arbitrary default value of 1/10 of page height.

ScriptX uses the default units of measure of the user's system. In a broad network environment default units are certain to vary (they could be either inches or millimeters) so you may wish to specify a fixed unit of measure with the licensed function SetMarginMeasure.

The bottomMargin property is part of the basic freely-distributable printing subset.

Syntax

printing.bottomMargin = numMargin

currentPrinter

Description

Specifies the printer to print to. Only the exact printer name strings as they appear on Internet Explorer's Print dialog can be specified. If the string does not exist or is written incorrectly, printing will be directed to the default printer.

Settings

This a read/write property. With JScript, take care to double a backslash if one appears in the printer name, as in the example below.

Usage

The internal implementation of writing to the currentPrinter property is the same as writing to the printer property, other than the implementation ofcurrentPrinter does not 'eat' any error. Therefore an error in currentPrinter will be reported in the same way as any other error that occurs in an ActiveX object property/method call.

onafterprint

Description

Event handler to be called when print spooling is done. The event is applicable to the results of a Print call but not to that of a PrintHTML call. It can be used to update the user interface accordingly. It is similar to the WaitForSpoolingComplete blocking call, but is asynchronous.

Note the difference between ScriptX's onafterprint event and the DHTML window.onafterprint event: the latter occurs after Internet Explorer has just made a document snapshot for printing and not after the actual print spooling job (see PRB: onafterprint Event Fires Before the Print Dialog Box Appears). So these two events are not interchangeable.

In fact, the DHTML window.onbeforeprint and window.onafterprint exist to give the document's script a chance to customize DHTML content before it goes to print-out or preview (and not to signal actual printing). The same effect can be achieved with the CSS  media=print or media=screen specific styles. Check out the following InsideDHTML.com articles: Printing Techniques, Using CSS to specify alternate document to print out.

Syntax

printing.onafterprint = function_object

Settings

This is a read/write property.

Applies To

Example

<script defer>
factory.printing.onafterprint = AfterPrint;

function AfterPrint() {

onbeforeunload

Description

String to prompt a user with when spooling (or a download originated by a PrintHTML call) is still in progress but the page is being closed or navigated away. By default, ScriptX waits 5 seconds in blocking mode to let spooling complete, then prompts the user with the choice to cancel the printing process. The user may decide to wait for another 5 seconds, and so on.

Note: to suppress the prompt you can force the blocking wait state with WaitForSpoolingComplete after any Print or PrintHTML call or before leaving the page. However the use of WaitForSpoolingComplete() after each PrintHTML call in a sequence of calls is not recommended. Use it only after the last call in the sequence.

Methods and Functions

BatchPrintPDF (ScriptX Corporate 32 bit Edition)

Description

Downloads Adobe Acrobattm or Microsoft Officetm files and prints them out in batch mode in the background. Any number of print-outs can be queued.

For Microsoft Officetm files, BatchPrintPDF prints only on the default printer using default settings.

For Adobe Acrobattm files, relevant current printing settings are used as described in the syntax section.

This updated functionality now requires v6.6 or later of ScriptX Corporate 32-bit Edition and an Enhanced PDF Printing license.

Please contact MeadCo sales for details.

Use IsSpooling to check if there are any outstanding downloads in the queue created by BatchPrintPDF. Use WaitForSpoolingComplete to wait for all documents to be downloaded and spooled.

Syntax

printing.BatchPrintPDF(url)

ParameterDescription
urlThe url of the document to be printed.

For Adobe Acrobattm files, the following printing settings are used:

printing.printer
printing.paperSize
printing.paperSource
printing.portrait
printing.copies
printing.collate
printing.duplex
printing.SetPrintScale(-1). 
    [The use of SetPrintScale(-1) enables "Shrink to Fit" of the printed output. Also, rotate pages to fit on the output medium, and center on the page is set. Any other value given to SetPrintScale is ignored.] printing.SetPageRange(false,startPage,endPage) to set the page range to print.

These settings are used per file submitted to the batch, so each document can be printed using different settings, for example, each document to a different printer.

Example

Here is a basic example of BatchPrintPDF use

<body>
<script>
function BatchPrintPDF(url) {
  factory.printing.SetPrintScale(-1); // ensure shrinks to fit if needed
  factory.printing.BatchPrintPDF(url);
}
</script>
<button id="idPrint" onclick="BatchPrintPDF('report.pdf')">BatchPrintPDF('report.pdf')</button>

printDocument  (v6.3.436 and later)

Description

Loads the specified file and sends the content directly to the printer. The file bytes are not rendered in any way, they are sent to the printer for the printer to interpret. In this way, postscript can be sent directly to the printer or label printing commands.

This method is synchronous; it will not return until the file load and print is complete.

Syntax

rawPrinting.printDocument(url)

ParameterDescription
url(String) url of the file whose contents are to be sent to the printer. The url must be absolute but may refer to local (file://) resources.

Return Value

none.

Applies To

rawPrinting

Examples

The following simple but complete example shows how to print a label stored on the web server to a Zebra printer. The sample is assuming that some process has run on the server to generate and store the required label.

PrintHTML

Description

Prints either specified HTML text or the HTML or XML document specified by the URL using the current printing settings in the same session context. The method is asynchronous. It returns before the document is downloaded and printed.

Important note:

The html to be printed must not be 'ScriptX-enabled' - it must not contain an object tag referencing the ScriptX object nor script code that uses that object. Attempting to print html (either specified html text or document specified by url) that contains the ScriptX object can lead to strange errors and failure of the entire printing process, including causing Internet Explorer to stop responding.

PrintHTML may be used to organize a printing queue in a separate process, in which case the current window may be closed without waiting for pending downloads to complete. See OwnQueue for more details.

Syntax

printing.PrintHTML(url[, prompt = false])

ParameterDescription
url(String) URL/html text to print:
ProtocolPrints
html://The html is loaded and printed, e.g. html://<html><head><title>Dynamic Printing</title></head><body>Hello world!</body></html>
any other, e.g. http://, https:// or if no protocol specified.The document is downloaded and printed. A relative (to the current page) url may be given.

Note: The target document at 'url' must NOT be 'ScriptX-enabled'.
prompt(Bool) Specifies whether or not the user should be prompted before the download is queued

Return Value

Returns false if printing with a prompt and the user cancels the printing.

Applies To

printing

Examples

[ JSP ] 게시판 페이징 처리 로직 JSP

반응형

http://blog.naver.com/wldud_0729/150015317564

매번 페이징을 구현할 때마다, 한 두시간 씩 끙끙대는 것 같다.

생각을 의사코드로 적은 후에 그걸 코드화 하는 습관을 들여야하는데,

성질이 급해서 일단 생각을 코드화 해서 버그를 잡은 다음에.. 그제서야 의사코드로 적고 있다.

다음은 생각의 흐름를 정리해본 것이다.

************************************************************************************************


 총 데이터 수가 37개인 데이터를 페이징 처리 해보자.

 데이터는 DB에서 가져오거나 xml파일을 읽어올 것이다.

  페이지를 3 페이지씩 보여줄 수도 있고 [1] [2] [3] [다음]

 혹은 10페이지씩 보여줄 수도 있다. [1] [2] [3] [4] [5] ...[10] [다음]

 값 셋팅에 따라 달라질 수 있도록 페이지그룹 사이즈(pageGroupSize) 변수를 사용하겠다.

 셋팅할 수 있는 값이 페이지그룹 사이즈 말고 또 무엇이 있을까?

  한 페이지 당 보여주는 리스트 갯수도 변할 가능성이 많다.

 이것은 페이지 사이즈(pageSize) 변수로 놓자.

 그러면, 페이징 로직의 결과를 예측하기 위해서 이 두개의 변수에 값을 넣어보자.

less..

 총 데이터 갯수 (count): 37

 페이지그룹 사이즈 (페이지그룹을 몇개씩 묶을 것인가) : 3
 페이지 사이즈 (한 페이지 당 리스트 갯수): 4

 이렇게 셋팅을 할 경우, 나오는 결과는?

 총 페이지 수(pageCount)는 37 / 4 = 9.25 니까 10 페이지 되겠다.

  pageCount = (count / pageSize ) + ( count % pageSize == 0 ? 0 : 1); 

  => count % pageSize == 0 ? 0 : 1 이 수식을 풀어서 쓰면

            if(count % pageSize == 0)
                return 0;
            else
                return 1;

    이렇게 표현된다.

 =============================================================================
                                       
          [1][2][3]   [4][5][6]   [7][8][9]   [10]
 페이지그룹넘버(numPageGroup) :   - 1 -           - 2 -           - 3 -      - 4 -
 =============================================================================
 
 페이지 그룹은 위와같이 총 4개로 나올 것이다. (pageGroupCount : 4)

 이 페이지 그룹을 본 후, 현재페이지가 호출될 경우를 생각해보면

 5페이지가 호출된다면 numPageGroup이 2인 상태로 페이지바가 보여질 것이다.

 그렇다면, 호출된 현재페이지를 가지고 페이지그룹넘버를 구하고,

 페이지그룹넘버값으로 페이지바의 첫번째 페이지를 계산해보자.

 numPageGroup = 올림(currentPage/pageGroupSize)

  => int numPageGroup = (int) Meth.ceil ((double)currentPage/pageGroupSize)                   

 => numPageGroup : 올림(5/3) = 2

 startPage = (numPageGroup - 1)*pageGroupSize + 1;

 => stratPage : (2-1)*3+1 = 4

 이제 시작페이지를 가지고 마지막 페이지도 구해보자

 endPage = startPage + pageGroupSize -1 => 4+3-1 = 6

 이런식으로 시작페이지와 마지막페이지를 구했다면, for문을 돌려서 페이지바를 출력할 수 있을 것이다.

 그런데, 마지막 페이지그룹을 위 공식대로 계산하면 endPage가 12페이지가 나온다.

  총 페이지수가 10개인데 12페이지까지 출력되면 안 될것이다.

 따라서, if문 처리를 추가해주자.

 if( 마지막페이지 > 총페이지 )
  마지막페이지 = 총 페이지    => endPage = 10

************************************************************************************************

로직은 자바 클래스로, 출력부분은 JSTL 코드로 작성했는데.. 페이징 부분 코드는 다음과 같다.
 

[ 자바 클래스 ]

          //한 페이지 당 보여줄 글 갯수

J2EE에서 한글

반응형

J2EE에서 한글

공식처럼 대부분의 사이트가 EUC-KR 인코딩을 사용한다. 그런데 EUC-KR이 올바른 한글 인코딩일까?

결론은 아니다. EUC-KR로는 한글을 모두 표현할 수 가 없다. 똠방각하, 펲시콜라 이런 글자가 안되는 한글 페이지라니... EUC-KR에서는 ?방각하 ?시콜라 처럼 보여진다. google에서 펲시콜라를 입력해보라, 아니 이 블로그만 보더라도... 어처구니없이 외국사이트보다도 세종대왕의 자손들이 만들고 운영하는 사이트들에서 한글이 제대로 쓰여지고 있지 않다.
완성형, 조합형으로까지 거슬러 올라가 전산상의 한글 구현에 대해서 구구절절 읊지 않더라도 한글 자모로 구성 가능한 문자가 표현되지 않는 character set이나 encoding을 사용하는 것은 올바른 습관이 아니라고 본다.

여타의 기술 자료나 QnA 등에서 그래도 앞서나간 사람들이 jsp한글...tomcat 한글... 이런 글에 몽땅 EUC-KR로 기술하고있는 것은 문제라고 생각한다.

마땅히 한글 표현이 우수한 UTF-8를 사용해야한다. 한글 뿐만 아니라 국제화를 고려한다면 더더욱.

Tomcat에서 contentType을 UTF-8으로 하는 경우 jsp 파일은 UTF-8인콩딩으로 작성되어야한다. Eclipse를 사용한다면 문서의 Properties에서 수정할 수 있다. UTF-8인경우 한글 출력 및 post로 submit된 한글 값도 문제가 없지만 get 으로 전송된 파라미터 값은 한글이 깨진다.

Tomcat의 url decoding 과정에서 한글 처리에 문제가 있다.

String qry = request.getQueryString();
msg = URLDecoder.decode(qry.split("msg=")[1],"UTF-8");
out.println(msg)

처럼 직접 url decoding을 하면 get 전송된 한글도 정상적으로 출력된다.

request.getParameter()에서 UTF-8으로 decoding되지 않는 문제를 ... 음. 시간이 날 때 좀 더 파헤쳐보면 해법을 찾을 수 있을 거 같다.
꼭 찾아야지.

JSP 페이지 이동 4가지 방법 및 특성

반응형

① JavaScript를 이용

window.open, location.href, location.replace 등을 이용할수 있습니다


login_process.jsp

<% if (a == null) { %>

      <script>location.href = "admin.jsp"; </script>

<% } else { %>

      <script>alert('권한이 없어요!'); window.history.back(); </script>

<% } %>

         

특징적인부분은 브라우져의 주소창이 변경되며

(이말은 즉슨 클라이언트가 다시 admin.jsp를 서버에 요청한다는 말입니다)

login_process.jsp 에서 jsp가 다 실행되고 브라우져에 out put된 html 및 javascript들만으로

실행된 코드들이라는 것입니다


② response.sendRedirect를 이용

login_process.jsp

<% if (a == null) {

          response.sendRedirect("admin.jsp");

     } else {

          response.sendRedirect("login.jsp");

     }


     a = "test 입니다";

     System.out.println(a);

%>


이 코드에서 a가 출력될까요 안될까요?

출력 됩니다.

sendRedirect가 되더라도 밑에 jsp 코드들은 모두 실행 된다는 말입니다

response.sendRedirect는 기본적으로 모든 로직들을 다 처리한 후 코드 맨 마지막 부분에

사용하는 것이 올바른 방법입니다

만약 그렇지 못한 경우는 response.sendRedirect 다음 바로 return; 이라는 코드를 집어 넣어야 합니다


response.sendRedirect은 HTTP 헤더정보를 변경하여 redirect시키기 때문에 역시 브라우져의 주소창이 변경되며 sendRedirect가 실행되기전 html이나 javascript로 out put되는 코드들은 모두 실행되지 않습니다.


③ forward 이용

jsp 태그의 <jsp:forward> 나 servlet의 RequestDispatcher.forward 를 이용할수 있습니다


login_process.jsp

<% if (a == null) { %>

          <jsp:forward page="admin.jsp"/>

<% } else { %>

          <jsp:forward page="login.jsp"/>

<% }


     a = "test 입니다";

     System.out.println(a);

%>


그럼 위의 코드의 경우 a가 출력 될까요 안될까요?

정답은 출력 안됩니다. 바로 forward 되어 버립니다.

클라이언트로 응답주지 않고 바로 서버측에서 admin.jsp로 이동하기 때문에

주소창이 바뀌지 않고 그로인해 브라우져에 출력되는 응답속도 또한 사용자가 보기에는

응답이 빠른 장점이 있습니다


하지만 forward 이후 JSP 코드들이 실행되지 않는것 사실이지만 만약 finally절이 있는경우

finally절은 실행 됨으로 확실히 알아둡시다.


④ meta 태그 이용

마지막으로 meta 태그를 이용할 수도 있습니다.


<META http-equiv=refresh content="0;url=admin.jsp">


즉 요약하자면..

페이지 이동 방법이 여러가지가 있습니다.

그 특성들을 잘 알고 올바르게 사용하여야 합니다

Tomcat 5.5 에서 JNDI Datasource 사용하기

반응형
Tomcat 5.5 에서 JNDI Datasource 사용하기
JSP 프로그래밍에서 쉽게 볼 수 있는 DB를 사용하는 방법대신 왜 DBCP, JNDI Datasource 같은 복잡한 것들을 왜 해야할까요?

DBCP, JNDI에 대한 자세한 정의는 따로 위키등에서 참고하세요.

- DBCP는 데이터베이스 커넥션풀링으로 접속객체를 풀에 넣어두고 필요할때 꺼내서 사용하여 성능을 향상시키기 위함입니다.
- JNDI(Java Naming and Directory Interface)는 분산된 자원을 디렉토리 형태로 이름지어 검색할 수 있게 하는 것입니다.
- 톰캣의 JNDI Datasource 라는 것은 데이터소스를 JNDI를 이용, 찾아서 연결해 사용하자는 것입니다.

JNDI Datasource를 이용하면 웹어플리케이션 자체에 DB접속을 위한 잡다한 코드를 넣지 않아도 되므로 환경변화에 유연합니다.

우선 컨텍스트(Context)에 데이터소스를 적어줘야 합니다.
컨텍스트 파일의 작성에 대해서는 Tomcat 5.5에서의 <Context>를 참고하시기 바랍니다.
컨텍스트에 아래와 같이 Resource를 자신의 환경에 맞게 적어줍니다.
<?xml version="1.0"?>
<Context docBase="yourapp" path="/yourapp">
	<Resource description="Test database connection" 
	       name="jdbc/TestDB" auth="Container" type="javax.sql.DataSource"
               maxActive="100" maxIdle="30" maxWait="10000"
               username="yourid" password="yourpw" driverClassName="com.mysql.jdbc.Driver"
               url="jdbc:mysql://localhost:3306/mydb?autoReconnect=true"/>
</Context>
위에서 driverClassName은 로드할 드라이버를 설정하는 부분입니다.
driverClassName와 url의 값은 Java에서 일반적인 DB 접속시 많이 쓰던 것임을 알 수 있습니다.
name은 프로그램 코드에서 이 데이터소스를 참조하기 위한 이름입니다.

위에서 com.mysql.jdbc.Driver를 사용하였는데 이런 jdbc 드라이버는 톰캣의 기본 라이브러리가 아니므로 $CATALINA_HOME/common/lib 디렉토리에 mysql-connector-java-버전-bin.jar 파일을 넣어줘야 합니다.
DBCP를 위해 필요한 라이브러리는 톰캣에 기본으로 존재하며 naming-factory-dbcp.jar 입니다.

DB 드라이버를 로드하고 DBCP에 대한 복잡한 설정을 하는 프로그램 코딩 없이 설정파일에 기술하는 것만으로 JNDI Datasource로 DBCP를 이용하는데 필요한 준비는 끝났습니다.

이제 간단한 소스를 실행하여 문제없이 동작하는지 테스트 해보겠습니다.

import javax.naming.InitialContext;
import javax.sql.DataSource;

try {
    InitialContext initContext = new InitialContext();
    Context envContext = (Context)initContext.lookup("java:/comp/env");
    DataSource ds = (DataSource)envContext.lookup("jdbc/TestDB"); //위에서 설정한 데이터소스의 name
   
    Connection conn = ds.getConnection();
    System.out.println(conn);
    conn.close();
} catch(Exception e) {
    e.printStackTrace();
}

위의 코드에 문제가 없다면 org.apache.tomcat.dbcp.dbcp.PoolableConnection@15d4de6 와 같은 결과가 출력됩니다.
이제 Connection 객체를 이용해서 기존과 똑같이 데이터베이스 관련 코딩을 하면 됩니다.

JNDI를 이용하여 DataSource를 가져오는 방법은 톰캣만이 가능한것이 아니라 다른 WAS들도 가능합니다. 참조하는 name을 일치시켜주면 기존 프로그램의 코드수정 없이 WAS의 설정파일만 수정하면 됩니다.

* Name [jdbc/TestDB] is not bound in this Context 에러가 발생하면 jdbc/TestDB(해당이름)를 JNDI가 찾을 수 없다는 것으로써 설정의 name이 틀리지 않았는지 확인해보고 문제가 없다면 컨텍스트 파일을 못읽는 것일 수 있으므로 컨텍스트 파일의 위치와 파일명을 확인합니다.

* web.xml의 <resource-ref> 설정에 대한 자료도 봤는데 설정하지 않더라도 동작에 문제가 없었습니다.

우분투를 개발 머신으로 만들기 - JSP 환경 구축 -

반응형
출처 : http://passion818.tistory.com/84

정말 오랜만에 글을 쓰네요..일본에서 돌아오고는 완전히 초 귀차니즘이..;;;
요즘은 우분투를 프로그램 개발용으로 쓰려고 별 짓을 다하고 있는 덕에 이렇게 블로그 등에 기록해 두지 않으면 좋지 않은 머리로 다 기억 못할거 같아 지금까지 삽질하며 구축한 내용을 글로 남기려고 합니다.

일단 시작은 본편인 JSP 환경 구축부터 해서 C/C++, Flex3, APM 설치 등의 순으로 글을 쓰려고 합니다.
우분투 버전은 9.04 Jauty이고 제가 참고 한 자료들이 대부분 8.04이후의 글들을 참고 하였으므로 8.04나 8.10도 잘 될거라고 예상됩니다.
그럼 본 내용으로 들어가보도록 하지요..

[ 참고한 글들 ]

1. JDK 6 설치

JSP 환경을 구축하는데 JDK는 당연히 빠질 수 없겠지요..ㅎㅎ. 여기서 사용할 JDK 패키지는 sun-java6-jdk 패키지로 시냅틱에서 jdk로 검색을 하여 설치하면 아주 간단히 설치가 가능합니다. 예외적인 상황으로는 오픈오피스의 의존성 관계로 OpenJDK가 설치되어 있을것인데 위의 패키지를 설치한 후엔 다음 명령으로 기본 Java를 변경해 주시거나 OpenJDK를 삭제하시면 됩니다.
$ sudo update-alternatives --config java
jdk-doc은 무슨 이유에서인지 에러를 뿜으며 설치가 안되는군요..뭐..api는 자바 사이트에서 보면서 해도 되니 doc은 패스..ㅡㅡ;

JAVA 환경변수 등록
$ sudo gedit /etc/profile

다음 내용을 추가하고 저장
export JAVA_HOME=/usr/lib/jvm/java-6-sun

source명령으로 수정한 profile를 반영합니다.
$ source /etc/profile

2. Tomcat 설치

이제 Java 구동 환경은 구축 되었으니 JSP파일을 구동 시킬 서버를 구축해줘야 하는데 그 역할을 하는 것 이 톰캣 서버이지요.ㅎㅎ 윈도우는 그냥 냅다 다운받아 설치하고 실행시키면 되지만 우분투는 쪼끔 귀찮게 하더군요..ㅡㅡ;;
원 래는 시냅틱에서 검색하여 패키지로 설치하려 했으나..이게 이클립스와 연동시키려니 이래저래 해줘야할 것도 많고 구글 검색을 통해 제가 해본 방법으로는 잘 안되서 결국 리눅스용 톰캣을 인터넷으로 다운받아 설치했습니다. 실제로 서버를 구축해서 서비스를 한다면 추천하고 싶지 않은 방법이지만 단지 공부등의 이유로 간단히 자신의 컴에 JSP구동 환경을 구축하려고 한다면 이방법이 제일 간편할 듯 싶군요.
 
우선 톰캣을 다운로드 합니다. 저의 경우에는 Tomcat 6 버전을 다운로드하였습니다.(교육 과정에서 이 버전을 써서요..ㅎㅎ;;)

다운로드한 디렉토리에서 다음 명령을 입력해 압축을 해제합니다.
$ tar xvfz apache-tomcat-6.0.20.tar.gz

압축 해제한 톰캣 디렉토리를 적당한 위치로 옮깁니다. 저의 경우엔 /usr/local/tomcat6이란 디렉토리를 만들어 옮겼습니다.
$ sudo mkdir /usr/local/tomcat6
$ sudo mv ./apache-tomcat-6.0.20/* /usr/local/tomcat6/

이것으로 톰캣의 설치는 끝났습니다. 이제 톰캣을 구동시키고(Start) 정지시키고(Stop) 재시작(Restart)시킬 스크립트를 작성합니다.
$ sudo gedit /etc/init.d/tomcat6

다음 내용을 입력 후 저장합니다.
export JAVA_HOME=/usr/lib/jvm/java-6-sun
case $1 in
start)
sh /usr/local/tomcat6/bin/startup.sh
;;
stop)
sh /usr/local/tomcat6/bin/shutdown.sh
;;
restart)
sh /usr/local/tomcat6/bin/shutdown.sh
sh /usr/local/tomcat6/bin/startup.sh
;;
esac
exit 0

만든 스크립트 파일을 실행 가능하도록 권한을 부여하면 시냅틱으로 설치한 톰캣 서버처럼 구동이 가능합니다.
$ sudo chomod 755 /etc/init.d/tomcat6
$ sudo /etc/init.d/tomcat6 start
       stop
       restart 이런식의 구동이 가능하게 됩니다.

저 같은 경우에는 이클립스에서 구동하고 정지 시킬 것이기에 톰캣이 우분투가 시작하면서 자동으로 실행 될 필요가 없지만 혹시나 자동으로 실행되길 바라신다면 다음 명령을 추가로 입력하여 링크를 겁니다.
$ sudo ln -s /etc/init.d/tomcat /etc/rc1.d/K99tomcat
$ sudo ln -s /etc/init.d/tomcat /etc/rc2.d/S99tomcat

3. Oracle 10g XE 설치

오라클의 경우엔 저장소가 있기 때문에  소스리스트에 저장소를 추가 후 시냅틱이나 터미널에서 apt-get install 명령으로 간단히 설치가 가능합니다. 원래는 데비안용 패키지인것 같지만 우분투 자체가 데비안을 기반으로 만든 것이여서 그런지 아무 문제 없이 설치가 가능합니다.

시스템 > 관리 > 소프트웨어 소스에서 써드 파티 소프트웨어 탭에서 다음 저장소를 추가합니다.
deb http://oss.oracle.com/debian unstable main non-free #Oracle 10g Express Edition

8.10부터 저장소를 추가하면 해당 저장소의 인증키가 있어야 되는데 오라클의 경우 터미널에서 다음 명령으로 키를 얻어옵니다.
$ sudo wget http://oss.oracle.com/el4/RPM-GPG-KEY-oracle  -O- | sudo apt-key add -
$ sudo aptitude update

이제 오라클을 설치하면 되는데 다국어 지원을 위해 universal버전을 설치합니다. ( 시냅틱에서 oracle로 검색하여 설치하셔도 무방합니다. )
$ sudo aptitude install oracle-xe-universal

설치가 끝나면 이제 본인의 컴에 맞게 설정을 해야겠죠? 다음 명령으로 설정을 합니다.
$ sudo /etc/init.d/oracle-xe configure

다음은 설정 화면으로 [Enter]라고 쓰인 부분에서 엔터키를 치면 기본 설정값을 쓰겠다는 의미입니다. 포트 설정의 경우 톰캣이 8080포트를 사용해야 하므로 포트 충돌을 막기 위해 8087로 설정합니다.
Oracle Database 10g Express Edition Configuration
-------------------------------------------------
This will configure on-boot properties of Oracle Database 10g Express
Edition.  The following questions will determine whether the database should
be starting upon system boot, the ports it will use, and the passwords that
will be used for database accounts.  Press <Enter> to accept the defaults.
Ctrl-C will abort.

Specify the HTTP port that will be used for Oracle Application Express [8080]: 8087

Specify a port that will be used for the database listener [1521]: [ENTER]

Specify a password to be used for database accounts.  Note that the same
password will be used for SYS and SYSTEM.  Oracle recommends the use of
different passwords for each database account.  This can be done after
initial configuration:
Confirm the password:

Do you want Oracle Database 10g Express Edition to be started on boot (y/n) [y]: [ENTER]

Starting Oracle Net Listener...Done
Configuring Database...Done
Starting Oracle Database 10g Express Edition Instance...Done
Installation Completed Successfully.
To access the Database Home Page go to "http://127.0.0.1:8087/apex"
pcandme@behemoth:/etc/apt$ sudo /etc/init.d/oracle-xe configure
Oracle Database 10g Express Edition is already configured

설정이 끝났으면 오라클도 역시 환경변수를 등록합니다.
$ sudo gedit /etc/profile

다음 내용을 추가합니다.
ORACLE_HOME=/usr/lib/oracle/xe/app/oracle/product/10.2.0/server
PATH=$PATH:$ORACLE_HOME/bin
export ORACLE_HOME
export ORACLE_SID=XE
export NLS_LANG='KOREAN_KOREA.AL32UTF8'

source명령으로 수정한 profile를 반영합니다.
$ source /etc/profile

여기까지 끝났으면 웹브라우저에 다음 주소를 입력하여 제대로 설치가 되었는지 확인합니다. 올바르게 설치가 되었다면 로그인 페이지가 나올 것입니다.
http://127.0.0.1:8087/apex


4. Eclipse 설치

금방 끝날줄 알았더니 이거..상당히 길어지네요..;; 이제 JSP구동 환경도 구축 되었고 데이터베이스를 구축할 오라클도 설치가 끝났으니 JSP 개발을 위한 IDE인 이클립스를 설치하도록 하지요. 설치할 버전은 3.4 Ganymede 입니다. 우분투의 기본 저장소에 있는 이클립스는 이상하게 아직도 3.2버전을 고집하고 있더군요..ㅡㅡ;; 나중에 플렉스도 설치해야 하므로 전 이클립스 공시 홈페이지에서 Eclipse J2EE버전을 다운로드하였습니다.( 플렉스 설치할 때 알았지만..3.4버전이..버그가 많더군요..;; 뭐 심각한건 없었으므로 괜찮았지만 쪼금 삽질을 했다는..;;; )

톰캣이 정상적으로 설치가 되었다면 이클립스와의 연동은 간단합니다. 다운로드한 이클립스를 압축해제 후 적당한 위치로 옮깁니다. 저는 홈 디렉토리로 옮겼습니다.( 권한 설정등이 귀찮아서..ㅡㅡ;; )


이클립스를 구동하면 퍼스펙티브가 J2EE로 기본 설정되어있어 아래와 같이 화면 하단에 보면 서버탭이 보이실겁니다.


저는 이미 설정을 해서 위와 같이 나왔지만 처음 설정할 때는 위의 서버 탭에서 오른쪽 클릭 > new를 해주시면 다음과 같은 창이 뜨는데 서버 목록에서 Apache를 누르면 연동 가능한 톰캣 목록이 뜹니다.


Tomcat 6버전을 선택하고 Next를 누르면 톰캣이 설치된 경로와 JRE버전을 선택하는 화면이 나오는데 JRE는 기본 그대로 놔두셔도 되지만 JDK를 여러버전이 설치가 되어있다면 사용할 JDK버전에 맞는 JRE를 선택해주셔야 합니다. 톰캣은 아까 설치한 경로를 입력해주시면 됩니다.


문제가 없다면 다음과 같이 서버가 추가 된 화면을 보실 수 있습니다. 서버 구동은 우측에 있는 플레이 버튼처럼 생긴 아이콘을 클릭해주시면 톰캣이 구동 됩니다.


이제 테스트를 위해 JSP 프로젝트를 하나 생성하여 테스트 페이지를 작성한 후 서버를 구동해 실제로 작동하는지 확인하면 되겠군요..
테스트 페이지 작성까지 글을 쓰면 너무 길어지므로( 이미 여기까지도 길지요..;; ) 생략하겠습니다.
이상으로 우분투에서 JSP환경 구축편을 마칩니다. 오랜만에 장문의 글을 쓰려니..힘드네요..@.@

JSP 파일의 동작구조

반응형

JSP 가 실행되기 위해서는 JSP 파일을 서블릿 파일로 변환하는 과정을 거치게 된다.
이 작업은 클라이언트의 요청이 있을 경우, 또는 JSP 파일이 변경되었을 경우 변경된
JSP 파일을 로딩하기 위해서 이루어진다.

JSP 동작구조
 
1.클라이언트가 jsp 페이지 요청
2. 웹 서버가 요청한 페이지를 를 처리하기 위해 JSP 컨테이너에게 처리를 넘긴다.
3. 해당 JSP 파일이 처음 요청된 것이면 JSP 파일을 서블릿으로 변환.
(JSP 컨테이너가 수행) 이전에 요청되었던 페이지일 경우 5 단계 실행
4.서블릿 파일은 자바에서 실행 가능한 상태인 클래스 파일로 컴파일
5. 클래스 파일을 메모리에 적재 후 실행
6. 실행 결과가 웹 서버에게 넘겨짐
7. 웹 서버는 브라우저가 인식할 수 있는 HTML 형태로 결과를 웹 브라우저에 응답
 
* jsp가 servlet으로 변환된 소스는 WAS마다 다르다
 
※ tomcat은 변환된 서블릿 소스를
C:\apache-tomcat-5.5.26\work\Catalina\localhost웹 어플리케이션 디렉토리\org\apache\jsp\jspsrc 에 저장
 
※ eclipse에서는

input 태그에서 type="image"는 form.submit 속성을 가지고 있어서 값을 무조건 넘겨준다.

 

'검색' 같은 이미지를 만들고 나서 type을 image로 하면 텍스트 박스를 검사 할 수 없음.

 

 

input 태그를 img 태그로 바꿔야 한다.

SQL에 parameter를 삽입하여 실행하는 기능

반응형

SQL에 parameter를 삽입하여 실행하는 기능

SQL에 parameter를 삽입하여 실행하는 방법이 있습니다.

String sSql = "select * from mytable where name = ? and address = ?";
Connection conn = get database connection;
PreparedStatement prestmt = null;
Statement stmt = null;
prestmt = conn.prepareStatement(sSql);
prestmt.setString(1,"Mike");
prestmt.setString(2,"LA");
rs = prestmt.executeQuery();
while (rs.next())
{
 xxx = rs.getString(1);
 yyy = rs.getString(2);
}

위와 같은 parameter name,address를 삽입하여 SQL을 실행할 수 있습니다.
실행되는 SQL은 다음과 같습니다.

select * from mytable where name = 'Mike' and address = 'LA'

위와 같은 방식으로 많은 개발자들이 web application을 개발합니다.
위와 같은 방식은 개발 생산성 측면에서 몇가지 문제가 있었습니다.
가장 큰 문제가 실제 실행되는 SQL을 개발자가 알 수 없습니다.
물론 parameter를 일일이 대입해서 볼수는 있지만 실제 값이 대입된 SQL을 개발자가 볼 수
없다는 것입니다.
문제가 되는 경우를 보겠습니다.

update mytalbe set name=? where id=?
prestmt.setString(1,"123456789012345678901234567890");
prestmt.setString(2,"2334");

그런데 mytable.name field는 varchar(16) 으로 선언이 되어 있다고 하겠습니다.
즉 입력한 값이 16 byte만 설정이 될 수 있습니다.
이와 같은 경우 개발자는 parameter가 설정된 실행되는 SQL을 trace log에서 볼 수 없기때문에
오류를 쉽게 파악하기 힘들 수 있습니다.

그래서 필자는 자체적으로 parameter가 설정된 SQL을 build하는 program을 개발해 보았습니다.
WCStmt.makeQuery method가 이것입니다.
parameter는 WCProperties로 전달하도록 하였습니다.

String sSql = "insert into table_name (name,address) values ('$name','$address')";
WCProperties pParam = new WCProperties();
pParam.setValue("name","jane");
pParam.setValue("address","L'A");
WCStmt oStmt = new WCStmt();
sSql = oStmt.makeQuery(sSql,pParam);

sSql 값 "insert into table_name (name,address) values ('jane','L''A')" 이와 같이 됩니다.
개발자는 sSql의 값을 확인하여 정확한 SQL이 생성되었는지를 점검할 수 있습니다.
그러나 개발을 하고 보니 이 방법도 몇가지 문제가 있었습니다.
parameter value값이 SQL에 삽입될때 몇가지 변환이 되어야 하는데 이 변환이
database의 type에 따라 약간씩 다르다는 것입니다.
L'\A 이와 같은 값이 있다고 하겠습니다.

- oracle,mssql : L''\A
update table_name set field_name = 'L''\A' where id = 37

- mysql : L''\\A
update table_name set field_name = 'L''\\A' where id = 37

이와 같이 변환이 되어야 합니다. 그래서 위의 makeQuery 함수를 다음과 같이 변경해야 했습니다.

String sDsn = "WDLDatabasePool";
sSql = oStmt.makeQuery(sSql,pParam,sDsn);

위에서 처럼 makeQuery에 database connection pool 이름을 전달하여 database type을 얻어와서
해당 database type에 대한 변환을 하도록 하였습니다.

jsp 페이지 이동 4가지 방법

반응형

먼저 다음 페이지 이동 특성들을 미리 알아볼 필요가 있습니다

JSP에서는 페이지 이동시 다음 4가지 정도의 방법이 있습니다


① JavaScript를 이용

window.open, location.href, location.replace 등을 이용할수 있습니다


login_process.jsp

<% if (a == null) { %>

      <script>location.href = "admin.jsp"; </script>

<% } else { %>

      <script>alert('권한이 없어요!'); window.history.back(); </script>

<% } %>

         

특징적인부분은 브라우져의 주소창이 변경되며

(이말은 즉슨 클라이언트가 다시 admin.jsp를 서버에 요청한다는 말입니다)

login_process.jsp 에서 jsp가 다 실행되고 브라우져에 out put된 html 및
javascript들만으로

실행된 코드들이라는 것입니다


② response.sendRedirect를 이용

login_process.jsp

<% if (a == null) {

          response.sendRedirect("admin.jsp");

     } else {

          response.sendRedirect("login.jsp");

     }


     a = "test 입니다";

     System.out.println(a);

%>


이 코드에서 a가 출력될까요 안될까요?

출력 됩니다.

sendRedirect가 되더라도 밑에 jsp 코드들은 모두 실행 된다는 말입니다

response.sendRedirect는 기본적으로 모든 로직들을 다 처리한 후 코드
맨 마지막 부분에사용하는 것이 올바른 방법입니다

만약 그렇지 못한 경우는 response.sendRedirect 다음 바로 return;
이라는 코드를 집어 넣어야 합니다


response.sendRedirect은 HTTP 헤더정보를 변경하여 redirect시키기
때문에 역시 브라우져의 주소창이 변경되며 sendRedirect가 실행되기전
html이나 javascript로 out put되는 코드들은 모두 실행되지 않습니다.


③ forward 이용

jsp 태그의 <jsp:forward> 나 servlet의 RequestDispatcher.forward 를
이용할수 있습니다


login_process.jsp

<% if (a == null) { %>

          <jsp:forward page="admin.jsp"/>

<% } else { %>

          <jsp:forward page="login.jsp"/>

<% }


     a = "test 입니다";

     System.out.println(a);

%>


그럼 위의 코드의 경우 a가 출력 될까요 안될까요?

정답은 출력 안됩니다. 바로 forward 되어 버립니다.

클라이언트로 응답주지 않고 바로 서버측에서 admin.jsp로 이동하기 때문에

주소창이 바뀌지 않고 그로인해 브라우져에 출력되는 응답속도 또한 사용자가
보기에는응답이 빠른 장점이 있습니다


하지만 forward 이후 JSP 코드들이 실행되지 않는것 사실이지만 만약 finally절이
있는경우finally절은 실행 됨으로 확실히 알아둡시다.


④ meta 태그 이용

마지막으로 meta 태그를 이용할 수도 있습니다.


<META http-equiv=refresh content="0;url=admin.jsp">


즉 요약하자면..

페이지 이동 방법이 여러가지가 있습니다.

그 특성들을 잘 알고 올바르게 사용하여야 합니다.

MultipartRequest 파일 업로드

반응형

www.servlets.com 사이트 에 접속한다. 


 

빨간 네모 박스가 쳐져 있는 부분을 클릭한다.

 

 

스크롤을 아래로 약간 내려 보면 DownLoad 부분이 나오는데 거기에서

Cos 로 시작되는 파일을 다운 받는다.

다운받은 압축 파일의 압축을 풀고

cos-05Nov2002/lib 안에 cos.jar 아카이브 파일을

자바 폴더와 톰켓 폴더에 각각 넣어주도록 한다.

 

C:/Java/jdk1.6.0_06/jre/lib/ext

C:/Java/jre1.6.0_06/lib/ext

C:/Tomcat5.5/common/lib

 

 

jsp 파일을 코딩시 폼양식에 enctype="multipart/form-data" 를 넣어주도록 한다.

ex ) <form name="form" method="post" enctype="multipart/form-data">

 

tip! enctype을 JavaScript 에서 제어하고 싶을시에는 아래와 같이 코딩해준다.

ex) 폼이름.encoding = "multipart/form-data"; 

    form1.encoding="multipart/form-data";

 

※ 주의 : enctype 을 지정해 주지 않으면 파일 업로드가 되지 않으며 톰캣의 내장객체 request 객체를 사용할 수 없다.

         정확히는 enctype 을 multipart/form-data 로 설정해 주었다면 톰갯의 내장객체 request 객체를 사용할 수 없다.

 

 1) MultipartRequest 를 사용하기 위해서는 com.oreilly.servlet 패키지를 import! 해야 한다.

   ex) <%@ page import! = "com.oreilly.servlet.*" %>

 

 2) MultipartRequest 는 객체를 생성하자 마자 파일을 업로드 시킨다.

   ex) MultipartRequest multi = new MultipartRequest(request, "파일 저장 경로(String)", 파일크기(int), "인코딩");

       // 이순간 업로드가 발생된다.

 

 3) MultipartRequest 를 사용 하게 되면 톰캣의 request 객체의 getParameter 메서드를 이용하여

   값을 전달 받지 못한다. 따라서 MultipartRequest를 사용하게 되면 값을 전달 받기 위해서는 MultipartRequest 객체의

   getParameter 메서드를 이용하여 값을 전달 받아야 한다.

   ex) String name = multi.getParameter("name");

 

 4) 파일을 저장할 경로는 직접 써주기 보다는 톰캣의 내장 객체인 application 객체의 getRealPath() 메서드를 사용하자.

    String savePath = application.getRealPath("파일을 저장할 폴더");

    ex) String savePath = application.getRealPath("/product");

        MultipartRequest multi = new MultipartRequest(request, savePath);

 

 5) 파일 이름을 받아올때는 MultipartRequest 의 getFileSystemName 메서드를 사용한다.

    String fileName = multi.getFilesystemName("파라미터 name");

    ex) String fileName = multi.getFilesystemName("fileName");

어디서 구해온 소스인데 이거 때문에 진짜 고생했다.

파일은 다운로드 되는데 getOutputStream 애러가 계속 나는 것이였다.

알고보니 이놈은 스페이스나 줄바꿈 뭐 이런게 들어가면 안되는 것이다.

<%...%><%...%> 요런식으로 다 붙여야 한다.

그리고 다운로드 취소시에 소켓 애러가 나는데 그건 무시하자. 그건 문도 안열었는데 닫으라고 하니까 나는거다.

InputStream과 OutputStream을 사용하는 경우 파일사이즈가 크면 java.lang.OutOfMemoryError이 발생하는 경우가 생겨, BufferedInputStream과 BufferedOutputStream을 사용하여 문제를 해결해 보았다.


JSP 다운로드 프로그램:


 try {
  String path = WEBConstants.SYSTEM_DOCROOT;
  File file = new File(path + filePath);


  response.reset() ;
  response.setContentType("application/x-octetstream");

  response.setHeader("Accept-Ranges", "bytes");
  response.setHeader("Content-Disposition", "attachment; filename=\"" + new String(fileName.getBytes(), "UTF-8") +"\"" );
  response.setHeader("Content-Length", ""+file.length() );

  BufferedInputStream in = new BufferedInputStream(new FileInputStream(file));
  BufferedOutputStream os = new BufferedOutputStream(response.getOutputStream());

  int read = 0;
  while((read = in.read()) != -1) {
   os.write(read);

JSP File Brows

반응형

http://www.j2eestudy.co.kr/ 에서 아키 (Archi)라는 분이 작성하신글입니다. 유용하게 쓰일 일이 있을것 같아서 퍼왔습니다.


-------------------------------------------------------------------


안녕하세요.

JSP File Brows입니다. 제가 만든건 아니구요.:-)


저작권은 첨부파일 내에 포함되어 있습니다.
윈도우탐색기(?) 기능과 비슷하구요. 설치가 간편하니까 시간있으신 분들은 한번 사용해 보세요.(추천!)

[설치 방법]
첨부파일 압축을 풀면 아래와 같은 파일이 있습니다.
Browser.jsp
example-css.css

웹서버 루트 아래 특정 디렉토리에 복사하시고 "http://localhost/Browser.jsp" 이런식으로 접근하시면 됩니다.

저는 톰켓에서 테스트해봤는데 잘 되었습니다.

선택된 파일 압축하는 기능도 있네요. ;-)
한글 지원은 안 되나 보네요.

잘 사용하시면 유용한 툴이 될 것 같네요.

Introduction

Introduction of this course

1. Presentation slides (0.5 hour)

Java EE Overview

The objective of this session is to give you a big picture of Java EE architecture and platform and get yourself prepared for the rest of the course.  You don't have to understand everything that is described in the presentation below.  If you get reasonably good idea on what Java EE is, that should be good enough to proceed.  Please browse through the Resources below.

There is no homework in the week #1.

1. Presentation slides (1 hour)

                                                                                                                              return to topics



Web Core Technologies: Servlets, JSP, and JSTL


Web Application Structure

In this session, you will learn how a typical Web application is built.  You will also learn the internal structure of Web application as well as web.xml file.

1. Presentation slides (1 hour)

2. Lab (1 hour) and homework - The hands-on lab is updated with NetBeans 6.1.
  • 4001_webappstructure.zip (Unzip it in a directory of your choice and read lab document from <unzip-directory>/webappstructure/index.html to proceed)
  • Online lab document (This is the same document you will find in the hands-on lab zip file)
  • Homework (This is the same homework you will find in the hands-on lab zip file)
  • Change log

                                                                                                                   return to topics

Servlet Basics


You are getting into a very important topic, Servlet.  I expect many of you who get exposed to the Servlet for the first time might feel overwhelmed by the amount of things you feel you have to absorb. Given that the Servlet technology is the most-used functionality of J2EE platform, there are in fact lots of things to learn. 

1. Presentation slides (2 hours)

2. Lab and homework (1 hour) 
3. Resources
                                                                                                                              return to topics

JSP Basics


I assume by now, most of you are relatively comfortable with building and deploying Servlet based Web applications.  In this session, you will learn basic concept of JSP (JavaServer Pages) which is as equally important Web-tier technology as Servlet.  You will also learn how to build a simple JSP pages using JavaBeans.

1. Presentation slides (2 hours)

2. Lab and homework (2 hours)
3. Resources
                                                                                                                              return to topics

Servlet Advanced


By now, you have reasonably good idea on how you can use basic features of Servlets and JSP to build Web applications.  In this session, you are going to learn advanced features of Sevlets, mainly filters and life-cycle events.

1. Presentation slides - ServletAdvanced (1 hour)

2. Presentation slides - Servlet 2.4 Enhancements

Expression Language


A primary feature of JSP technology version 2.0 is its support for an expression language (EL). An expression language makes it possible to easily access application data stored in JavaBeans components. For example, the JSP expression language allows a page author to access a bean using simple syntax such as ${name} for a simple variable or ${name.foo.bar} for a nested property.

JSP 1.2 Custom Tags - We are not covering this topic in this course


Since the introduction of JSP 2.0 style tag files, the JSP 1.2 style development of custom tags should be avoided whenever possible meaning if you can develop your custom tags using tag files, you should use tag files.  Because of that reason, we are skipping this topic in this course.

JSTL


The JavaServer Pages Standard Tag Library (JSTL) encapsulates core functionality common to many JSP applications. Instead of mixing tags from numerous vendors in your JSP applications, JSTL allows you to employ a single, standard set of tags. This standardization allows you to deploy your applications on any JSP container supporting JSTL and makes it more likely that the implementation of the tags is optimized.

JDBC, SQL



SQL

SQL is a standard computer language for accessing and manipulating relational databases.  Even though Java persistence technologies such as EJB 3.0 Java Persistence API (JPA) or Hibernate could insulate developers from having to know the detailes of SQL, it is still important to know the intricacies of SQL in order to be able to write highly performant Java EE applications which involves persisting data to the relational database.

JDBC

JDBC is standard Java API for accessing amdn manipulating relational database through SQL.  Even though Java persistence technologies such as EJB 3.0 Java Persistence API (JPA) or Hibernate could provide higher layer abstraction than JDBC, JDBC is still one of the most popular Java APIs for persisting data to the relational database.

Java EE 5 & EJB 3.0 & JPA



Introduction to Java EE 5


Java EE 5 is a major major release in the evolution of Java EE with lots of new features. It has a huge emphasis on the ease of development.  The ease of development features include using annotations instead of deployment descriptors, simplified EJB development, use of dependency injection for accessing resources, Java Persistence API (JPA), and annotation based Web service development.  The goal of this presentation and hands-on lab is to give you overall sense of the Java EE features.

EJB 3.0 Enterprise Beans


The new EJB 3.0 API makes software development easier by reducing and simplifying the amount of work required from the developer. In other words, fewer classes and less code. This is possible because more of the work is now performed by the container.

Java Persistence API (JPA) Basics


The Java EE 5 platform introduces the new Java Persistence API, which was developed as part of JSR-220. The Java Persistence API can also be used outside of EJB components, for example, in web applications and application clients, and also outside the Java EE platform, in Java SE applications.

JSP 페이지 이동 4가지 방법 및 특성

반응형

먼저 다음 페이지 이동 특성들을 미리 알아볼 필요가 있습니다

JSP에서는 페이지 이동시 다음 4가지 정도의 방법이 있습니다


① JavaScript를 이용

window.open, location.href, location.replace 등을 이용할수 있습니다


login_process.jsp

<% if (a == null) { %>

      <script>location.href = "admin.jsp"; </script>

<% } else { %>

      <script>alert('권한이 없어요!'); window.history.back(); </script>

<% } %>

         

특징적인부분은 브라우져의 주소창이 변경되며

(이말은 즉슨 클라이언트가 다시 admin.jsp를 서버에 요청한다는 말입니다)

login_process.jsp 에서 jsp가 다 실행되고 브라우져에 out put된 html 및 javascript들만으로

실행된 코드들이라는 것입니다


② response.sendRedirect를 이용

login_process.jsp

<% if (a == null) {

          response.sendRedirect("admin.jsp");

     } else {

          response.sendRedirect("login.jsp");

     }


     a = "test 입니다";

     System.out.println(a);

%>


이 코드에서 a가 출력될까요 안될까요?

출력 됩니다.

sendRedirect가 되더라도 밑에 jsp 코드들은 모두 실행 된다는 말입니다

response.sendRedirect는 기본적으로 모든 로직들을 다 처리한 후 코드 맨 마지막 부분에

사용하는 것이 올바른 방법입니다

만약 그렇지 못한 경우는 response.sendRedirect 다음 바로 return; 이라는 코드를 집어 넣어야 합니다


response.sendRedirect은 HTTP 헤더정보를 변경하여 redirect시키기 때문에 역시 브라우져의 주소창이 변경되며 sendRedirect가 실행되기전 html이나 javascript로 out put되는 코드들은 모두 실행되지 않습니다.


③ forward 이용

jsp 태그의 <jsp:forward> 나 servlet의 RequestDispatcher.forward 를 이용할수 있습니다


login_process.jsp

<% if (a == null) { %>

          <jsp:forward page="admin.jsp"/>

<% } else { %>

          <jsp:forward page="login.jsp"/>

<% }


     a = "test 입니다";

     System.out.println(a);

%>


그럼 위의 코드의 경우 a가 출력 될까요 안될까요?

정답은 출력 안됩니다. 바로 forward 되어 버립니다.

클라이언트로 응답주지 않고 바로 서버측에서 admin.jsp로 이동하기 때문에

주소창이 바뀌지 않고 그로인해 브라우져에 출력되는 응답속도 또한 사용자가 보기에는

응답이 빠른 장점이 있습니다


하지만 forward 이후 JSP 코드들이 실행되지 않는것 사실이지만 만약 finally절이 있는경우

finally절은 실행 됨으로 확실히 알아둡시다.


④ meta 태그 이용

마지막으로 meta 태그를 이용할 수도 있습니다.


<META http-equiv=refresh content="0;url=admin.jsp">


즉 요약하자면..

페이지 이동 방법이 여러가지가 있습니다.

그 특성들을 잘 알고 올바르게 사용하여야 합니다.

fn:escapeXml(string) stting에 XML과 HTML에서 특별한 의미를 가진 문자들이 있으면, XML엔티티 코드로 바꿔준뒤 문자열 반환
fn:indexOf(string, sbustring) string에서 substring이 처음으로 나타나는 인덱스 반환
fn:join(array, separator) array요소들을 separator를 구분자로 하여 연결해서 반환
fn:length(item) item이 배열이나 컬렉션이면 요소의 객수를 문자열이면 문자의 객수를 반환

jstl

반응형

1. 개요

  • JSP에서는 사용자가 태그를 정의해서 사용하는 것이 가능(Custom Tag)
  • Custom Tag중 자주 사용하는 것을 표준화 시켜 놓은 것을 JSTL
  • 작업을 수행하는 코드들을 태그로 간략화

2. JSTL을 사용하기위한 환경 설정

  1) http://jakarta.apache.org → downloads → Taglibs → standard 1.1 Taglib → 1.1.2.zip을 클릭하여 다운로드
  2) 압축을 풀어 jstl.jar, standard.jar 두 개의 파일을 톰캣홈\webapps\study\WEB-INF\lib폴더에 복사


3. JSTL 1.1 라이브러리


라이브러리

c

<c:tagname...

XML processing

http://java.sun.com/jsp/jstl/xml

x

<x:tagname..>

I18N capable formatting

Functions(함수)

http://java.sun.com/jsp/jstl/functions

fn

fn:functionName(....)

4. JSTL 1.1 라이브러리

1) JSTL Core

  • 변수 선언, 삭제 등 변수와 관련된 작업
  • if문, for문 등과 같은 제어문, 그리고 URL 처리등에 사용
  1. <%@ taglib %> 디렉티브

  1. <%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>

p649


    *** 태그

(1) <c:set>
  • JSP의 setAttribute와 같은 역할
  • 변수 설정

  1. <c:set var="varName" value="value" target="targetObjectName" property="propertyName" scope="{page|request|session|application}"/>
  2.   var : 변수명
      value : 변수 값
      target : 자바빈 객체명,Map 객체명
      property : property 명
      scope : 공유범위

      예1) <c:set var="abc" value=${20}>  변수 abc에 값 20을 설정

      예2) <c:set value="20" target="kkk" property="age"}

             객체 kkk의 property  age의 값에 20을 설정


(2) <c:out>
  • JSP의 표현식을 대체
  • 화면에 해당 변수값을 출력

  1. <c:out var="varName" default="defaultValue" escapeXml="{true|false}"/>
            var : 변수명
            default : 기본값
            escapeXml : true로 설정시(기본값) < > & ‘ “ 문자들을 각각 &lt;&gt;&amp;&#039;&#034;로 출력

    예1) <c:out value="${abc}"/> 변수 abc 값을 출력


(3) <c:remove>태그
  • JSP의 removeAttribute()와 같은 역할을 한다.
  1. <c:remove var="varName" scope="{page|request|session|application}"/>
          var: 변수명
          scope : 변수의 공유 범위

예1) <c:remove var="abc"/> 변수abc의 값을 제거

  1. <%@ page contentType = "text/html; charset=euc-kr" %>
    <%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
    <html>
    <head>
     <title>JSTL core 예제 - set, out, remove</title>
    </head>
    <body>
  2.  browser변수값 설정
      <c:set var="browser" value="${header['User-Agent']}"/><br>
      <c:out value="${browser}"/><p>
     browser변수값 제거 후
      <c:remove var="browser"/>
      <c:out value="${browser}"/>
    </body>
    </html>

(실습1) 수량과 단가 기억장소에 data를 기억한 후 금액을 출력하는 프로그램 작성
    금액 = 수량 * 단가



(실습2) 이름과 국어,영어, 수학 점수를 폼에서 입력 받아서
EL과 JSTL을 이용하여 다음과 같이 출력


xxx님의 총점은 xxx이고 평균은 xxx입니다.


(4) <c:catch>
  • body위치에서 실행되는 코드의 예외를 잡아내는 역할
  1. <c:catch var="errMag"/>

        var : 에러가 발생하면 변수에 에러메세지가 들어간다


(5) <c:if>
  • 조건문
  1. <c:if test="condition" var="varName" scope="{page|request|session|application}"/>

       test : 조건 판별식
       var : 변수명
       scope : 변수의 공유범위


     예)

  1. <c:if test="${country=='korea'}">
        This customer is based in korea.
    </c:if>

country 변수값이 'korea'이면 밑의 문장 출력


(6) <c:choose>(<c:when>,<c:otherwise>)태그
  • switch문과 비슷, 조건에서 문자열 비교가 가능
  1. <c:choose>
      <c:when test="조건>body 내용</c:when>
      <c:otherwise>body의 내용</c:otherwise>
    </c:choose>

 예)

  1. <%@ page contentType = "text/html; charset=euc-kr" %>
    <%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
    <html>
    <head>
    <title>JSTL core 예제 - if, choose, when, otherwise</title>
    </head>
    <body>
    <c:set var="country" value="${'Korea'}"/>
    <c:if test="${country != null}">
      국가명: <c:out value="${country}"/>
    </c:if>
    <p>
    <c:choose>
      <c:when test="${country == 'Korea'}">
         <c:out value="${country}"/>의 겨울은 춥다.
      </c:when>
      <c:when test="${country == 'Canada'}">
         <c:out value="${country}"/>의 겨울은 너무 춥다.
      </c:when>
      <c:otherwise>
         그외의 나라들의 겨울은 알 수 없다.
      </c:otherwise>
    </c:choose>
    </body>
    </html>

(실습1) <c:if> 사용
변수에 수를 기억시키고
 기억된값이 0보다 크면 ‘양수입니다’
                 0이면 ‘0입니다’
                 0보다 작으면 ‘음수입니다’ 출력


(실습2) <c:choose>이용
변수에 이름과 점수를 기억시킨 후 점수에 따라 수우미양가 출력
  (예: 90점 이상 100점 이하이면 수)


(7) <c:forEach>
  • 객체 전체에 걸쳐 반복 실행할 때 사용
  1. <c:forEach items="items" begin="begin" end="end" step="step" var="varName" varStatus="varStatus"/>

      items : 반복할 객체명
      begin : 시작값
      end : 마지막 값

submit 후 button 막기

반응형


<form action=\"http://phpschool.com\" onSubmit=\"this.submit.disabled=true\">
<input type=\"text\" name=\"test\">
<input name=\"submit\" type=\"submit\" value=\"전송\">
</form>
이렇게 해야겠네요 : )
Jun// type=image일때는 조금 다르게 동작하는거같습니다
그래도 disabled 속성은 있으니
<input type=\"image\" onClick=\"this.form.submit();this.disabled=true\" value=\"전송\">

====================================================================
IE6에선 확인할수 없지만.

일단 IE7에선 아래 처럼 적용.
<input type="submit" value=" 저장 " onClick="this.form.submit();this.disabled=true"/>
