JSTL problem, expressions not being evaluated in c:out

[Chris]

I'm just starting to use the Java Standard template library,
and I'm having a problem with my expessions being output
correctly by the cut tag.

I've followed all of the instructions for installing JSTL,
and I am using it under Tomcat 5.0.

Here is the relevant snippet from my JSP:

<%@ taglib prefix="c" uri="http://java.sun.com/jstl/core" %
<c:set var="browser" value="${header['User-Agent']}"/>
<cut value="${browser}"/>

When the page is rendered, I get the output
"${browser}" instead of the evaluated expression. What am I
doing wrong?
Thanks in advance

Change the <%@ taglib prefix="c" uri="http://java.sun.com/jstl/core" %>
to <%@ taglib prefix="c" uri="http://java.sun.com/jstl/core_rt" %> when
using JSP 2 (which Tomcat 5 does). Your code would be correct if you used
JSP 1.2 (Tomcat 4.X series) instead.

Also, you don't need the <cut> anymore in JSP 2, you can just type
something like
"browser = ${browser}"
