JSP 2.0 and JSTL question

Question

Hi,
I'd just like to ask if anyone could suggest a good site with tutorias about JSP 2.0 and more specific about requesting and manipulating attributes.
It is easy to do so by using servlets withn something like:
ArrayList mylist = (ArrayList)request.getAttribute("mylist");
and use it with an iterator.
...but I'd like to learn how I can request and manipulate ArrayLists in JSP using JSTL.
thanks in advance,
mike

All you should need are the <%@ taglib %> and the jar files in your web-inf/lib directory.
Nothing is required in web.xml for it to work.
Make sure you are using the JSTL 1.1 taglib URIs though: http://java.sun.com/jsp/jstl/core.
They look a lot like the old ones, but include /jsp now as well.
Does the EL evaluate inside a tag? eg <c:out value="${application.servletContextName}"/>
Couple of things to try
EL evaluation may be disabled: Put this at the top of your page:
<%@ page isELIgnored=false %>
Check your web.xml for something like this (disables EL in pages)
<jsp-property-group>
<url-pattern>*.jsp</url-pattern>
<el-ignored>true</el-ignored>
</jsp-property-group>
What version of the DTD are you using for web.xml? According to the JSP spec, if it is less than 2.3, and you haven't specified handling of the EL, it is ignored.
Relevant bits of the JSP2.0 spec: JSP3.3.2, JSP 1.10.1
Can you post some code which isn't working?
