Tomcat 5.0 JSTL 1.1 error when trying to loop over params

I'm running Tomcat 5.0 using jstl 1.1 and have examples from oreilly under my webapps folder that don't have any problems with the following code. Also, what is the best way to handle complex forms in JSP using JSTL? Could someone please help.
When I attempt to do something like this:

<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>

<c:forEach items="${param}" var="current">
      <c:out value="${current.key}" />
      <c:out value="${current.value}" />
</c:forEach>

I get this error:

Your code works for me.
I could not reproduce the error. Which version of java are you using ?
Are you sure that you have the 1.1 jars ?

currently using java 1.4.2

my WEB-INF/lib/ directory contains
jstl.jar and standard.jar that I got from the

webapps\jsp-examples\WEB-INF\lib directory that installed with tomcat

I just realized the code I posted doesn't run in their examples folder either.
Should I try to up date the jar files?

I got the freshest files from jakarta for jstl 1.1 and it still won't run for me.
The code does run under another folder that has an outdated jstl implementation..
but other things I'm doing don't run under that jstl implementation.

are you getting the same error with the new version of jstl?
