JSP 2.0 and JSTL EL

I have a Spring-based Application that was successfully running under Tomcat
5.5.

I've attempted to move it to JBoss 4.0.5, but it's having problems using the
JSP Expression Language (EL).

 

I made sure that I have the most recent JSTL 1.1 jstl.jar and standard.jar
files.

 

In the web.xml file I declare:

<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_4.xsd"

   version="2.4">

 

In the JSP page, I have the following:

 

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

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

 

But it continues to have a problem.  Spring says that it found the JSP 2.0
ExpressionEvaluator, but it can't find:

   org.apache.taglibs.standard.lang.support.ExpressionEvaluatorManager

 

I see this method in the JSTL version 1.0 standard.jar file, but not in the
version 1.1 file.

How can I figure out why and from where it is looking for that?
