John,
Another David here. I'm learning how to use the Expression Language 'stuff'
in Tomcat 5.0.X (.28 actually) under Struts v1.2.4 and I'm NOT using
Struts-El. I don't need it. I'm not sure about HashMaps as I haven't used
them yet, but I can access my variables without Struts-el this way:
My actual for in struts-config.xml is named "uploadForm". I'm sorry about
the stupid field called "name" but hey, I'm playing around with it! In my
upload.jsp page, I can access the members of the uploadForm either the old
way:
*** Keep in mind I still have a tag
*** <html:form action="/upload"> so the
*** below html:text tag works properly
*** and pulls the form bean in that is
*** associated with the /upload action.
<html:text property="name" />
OR I can do it using the JSP 2.0 expression language syntax:
<input type="text" name="name" value="${uploadForm.name}" />
Again, I DO NOT use Struts-el, just the stock struts. I do have one change
in my WEB-INF/web.xml file. Instead of having:
<webapp>
I changed it to:
<web-app xmlns="http://java.sun.com/xml/ns/j2ee"; version="2.4">
That change, after restarting my webapp, allowed me to use expression
language variables in any of my JSP files.
I hope this information helps you.
Regards,
David

Subject: Re: error in strutsel-exercise-taglib
Thanks for your reply, David. I'm not sure that I understand though. I
am using tomcat 5.0.x and JSP2.0. However, when I change the taglib
directive to:
<%@ taglib prefix="html" uri="http://jakarta.apache.org/struts/tags-html"%>
and try something like:
<html:img src="${images["iconClosed"]}" height="16" width="16"/>
(where images is a HashMap in request scope), I get an error. Indeed,
the documentation for the html:img taglib specifies a RTExpr.
Can you clarify for me?
Thanks!
