help with JSTL xml tags & tomcat

obinnahenreeAug 16 2008 — edited Aug 16 2008
hi, m learning JSTL and the core tags all work fine, but the xml tags throw the folowing exceptions while i try to deploy the JSP where i used them. i am using tomcat 5.5x and i also tried it tomcat 6.0x and same probs.
any suggestions will be welcomed. Sample code and exception below:

<%@ page contentType="text/html" %>
<%@ taglib prefix="c" uri="http://java.sun.com/jstl/core" %>
<%@ taglib prefix="x" uri="http://java.sun.com/jstl/xml" %>
<html>
<body bgcolor="lightblue">

<c:import url="books.xml" var="url" />
<x:parse xml="${url}" var="docs" />

---------------------------------<br>

<x:forEach var="n" select="$docs/books/book" >

<x:out select="n/title" /><br></br>
<x:out select="n/author" />
<br>========================

</x:forEach>

</body>
</html>

Shouldn't n/title and n/author be $n/title and $n/author?

Add the mentioned class (or in this case the JAR file with the mentioned class) to the classpath of the runtime environment and you'll be fine.

Find Xalan. I think it is from Apache.

p.s. If you noticed your first post actually through an "org/apache/xpath/XPathException" but now you get an error that says the class org/apache/xpath/XPathException can't be found! It obviously can be found because when an exception occurred the org/apache/xpath/XPathException was used. This happens because Java 5+ comes with Xalan but renames the packages to be com.sun.org.apache... and the XML tags that come with the Apache standard 1.1 tags don't know that. So you have to get Xalan and put it in the endorsed folder.

BalusC, you had provided a link to Maven and JSTL 1.2 on another thread. Does that implementation of JSTL require Xalan packaged separately?
