I. JSTL library

Standard.jar

Jstl.jar

two. TLD Configuration

1. Non-automatic loading mode

(1) Copy TLD file

Copy the TLD file to the Web-inf TLD folder

(2) Web.xml

<jsp-config>
<taglib>
<taglib-uri>http://java.sun.com/jstl/core</taglib-uri>
<taglib-location>/WEB-INF/tld/c.tld</taglib-location>
</taglib>
<taglib>
<taglib-uri>http://java.sun.com/jstl/fmt</taglib-uri>
<taglib-location>/WEB-INF/tld/fmt.tld</taglib-location>
</taglib>
<taglib>
<taglib-uri>http://java.sun.com/jstl/fn</taglib-uri>
<taglib-location>/WEB-INF/tld/fn.tld</taglib-location>
</taglib>
</jsp-config>

(3) referencing taglib in JSP

<%@ taglib prefix= "C" uri= "Http://java.sun.com/jstl/core"%>

2. Automatic loading mode

The Servlet2.4 specification provides automatic loading of TLD files, which are in the Standard.jar Meta-inf folder.

such as: C.tld file provides a description of the core JSTL tag

<taglib xmlns= "HTTP://JAVA.SUN.COM/XML/NS/J2EE"
Xmlns:xsi= "Http://www.w3.org/2001/XMLSchema-instance"
xsi:schemalocation= "Http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-jsptaglibrary_2_0.xsd"
version= "2.0" >

<DESCRIPTION>JSTL 1.1 Core Library</description>
<display-name>jstl core</display-name>
<tlib-version>1.1</tlib-version>
<short-name>c</short-name>
<uri>http://java.sun.com/jsp/jstl/core</uri>

You can see that its reference URI is Http://java.sun.com/jsp/jstl/core

Then reference taglib in the JSP as: <%@ taglib prefix= "C" uri= "Http://java.sun.com/jsp/jstl/core"%>
