Satish,
JBoss v4.0 says it (like Tomcat 5.X.X) supports JSP 2.0. So you can use the
standard Struts release and simply type in the ${expression} syntax from JSP
v2.0 directly into a struts tag or anywhere in the JSP page itself. Do
${abc.xyz} to call the getXyz method of object abc. Scopes should be
searched automatically in order as mentioned in previous posts today (or
yesterday) on JSP 2.0. For IF statements, you can do ${ true ? "right" :
"wrong" } where this prints out the word "right" while it could be a method
call to retrieve data to display instead of the string "right" or the string
"wrong". That makes a Standard struts tag like:
<html:text property="address" />
work the same as:
<input type="text" name="address" value="${someFormBeanName.address}" />
One trick: In Tomcat 5.X.X, (I don't know about JBoss 4.0) if you don't
configure a line in your WEB-INF/web.xml, JSP 2.0 syntax won't work unless
you add this to the top of your JSP (Note: this trick was posted to the list
within the last 24 hours):
<%@ page isELIgnored="false" %>
That trick was posted today. I just tried it with "true" and "false" and was
amazed. I suppose you'd use it with "true" if you had globally set JSP 2.0
on for your webapp but choose to selectively turn it off in particular JSPs
for some security reason. I just tried it and it's freaky/cool. :)
For an interesting JSP 2.0 reference card, try Sun at:

I hope this information helps.

David

Subject: Struts and EL/JSTL
Hello,
I am using JBoss 4.0 and Struts 1.2.4. I am interested in using EL/JSTL
along with Struts. However, I came across this comments by Karr, David (the
person who wrote the Struts-EL library) "Struts-el is intended to be used in
a JSP 1.2 container. It is not used in a JSP 2.0 container. I feel that
Struts-EL will certainly NOT become part of the core Struts tag library, as
there's no point to it."
Therefore, a simple question is do we use the tag libraries as declared in
struts-html-el.tld or c.tld etc? If not, how do we use something like <c:out
value="${abc.xyz}" />
It's very confusing.
Regards,
Satish Talim
