Hi, Michael.
Thank you very much. Your help makes me be sure about that there are some
version problems with my JSTL.
It's strange, in my WEB-INF folder, there are two 'tld' files for core lib.
One is c-1.0.tld, and another is c.tld. The uri in the former is '
http://java.sun.com/jstl/core', and in the later one is the same as you. But
I have to refer to the former one, or it will not work. And when I want to
output a value, I have to use <c:out value="${...}">, but not refer to EL
directly.
It seems that the JSTL version I use is 1.0, but in MANIFEST.MF in jstl.jar,
it shows that it's 1.1 version. I'm trying to figure out the reason now.
Bob

Song Chao,
I have no problem with this. Here is an example of what I am using in
my JSP:
<portlet:actionURL var="changeComponentUrl">
<portlet:param name="componentIndex"
value="${componentListStatus.index}"/>
<portlet:param name="componentId" value="${component.id}"/>
</portlet:actionURL>
My taglib definition is:
<%@ taglib uri="http://java.sun.com/jsp/jstl/core"; prefix="c"%>
What scope is your item object in? That could be the problem?
