JSTL : not working with JSP 2.0

Question

Hi
I was trying to run JSP 2.0 tag sample. here are the tag and jsp files.
wrapper.tag
<%@ tag body-content="scriptless" %>
<%@ attribute name="a" required="true" %>
<%@ attribute name="b" required="true" %>
<%@ attribute name="c" required="true" %>
<%@ attribute name="d" required="false" %>
<p> Header
<p> Attributes - ${a}, $, ${c}</p>
<table>
<tr>
<td>${a}</td>
<td>${b}</td>
</tr>
</table>
<p> Footer
---------- and my JSP is
main.jsp
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<%@ taglib prefix="tags" tagdir="/WEB-INF/tags" %>
<%@ taglib uri="http://java.sun.com/jstl/core" prefix="c" %>
<tags:wrapper a="1" b="2" c="3" >
<p> Wrapped Content
</p>
</tags:wrapper>
web.xml contents
<web-app 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-app_2_3.xsd"
version="2.3">
when I ran main.jsp I am getting
Attributes - ${a}, ${b}, ${c}
instead of Attributes - 1,2,3
the values are not being evaluated. Any suggestion/help would be appreciated. I used version 2.4 also. but i am getting this error
"According to TLD or attribute directive in tag file, attribute value does not accept any expressions" when using 2.4.
Any idea??
Thanks

As well as updating your web.xml to 2.4, you need to update the URI so that you use JSTL1.1 instead of JSTL1.0
If you are using JSP2.0 you should use JSTL1.1
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>[read this post reply #6 for more information|http://forum.java.sun.com/thread.jspa?threadID=629437&tstart=0]
