JSTL XML problem

Question

I use Tomcat 5.5.4, Jarkata JSTL 1.1.2, here is what I do:
(1) copy JSTL jar (standard.jar, jstl.jar) to tomcat common/lib directory
(2) create a jsp page like:
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%@ taglib prefix="x" uri="http://java.sun.com/jsp/jstl/xml" %>
<c:import var="data" url="sample.xml" />
<x:parse var="res" doc="${data}" />
if I print ${data}, it is correct XML file as I expected. But I always get [document:null] as XML parsing result.
Besides, whatever JSTL XML function I try, seems all of them give me error or null result.
Is there any special setting that I miss?
Why JSTL:core works and JSTL:xml doesn't?
Anyone have suggestion? Thanks!

Answer 1

To answer your questions from the previous post: No, I don't have Xalan.jar anywhere, unless it is packaged inside of some other jar, like one of the commons jars.
I am using Tomcat 5.0.29 or real close to it. Java 1.4.2.
A further question:
Do I really need copy c.tld and x.tld to WEB-INF/ and
set them up in WEB-INF/web.xml?
No. The tlds inside the JARs are all you need. I would get rid of these copies.
My understanding is: since you specify that uri:
http://java.sun.com/jsp/jstl/core, there is no need
to copy and set-up tld.
At least, if I remove them, JSTL:core works fine. As
for JSTL:xml, it doesn't work either way.What version of the web descriptor are you using? Version 2.3 or 2.4? It should either be defined is a <?DOCTYPE... ?> tag (v 2.3) or in the <web-app ...> tag (v. 2.4). You should be using the vs. 2.4.
I don't know if that would make a difference though...
