Here's what I usually do:
request.setAttribute( Constants.USER, userObject );
and the Constants.java defines
public final static String USER = "theUser";
then in the JSP
<c:out value="${theUser.name}"/>
But I want to be able to do something like
<c:out value="${Constants.USER.name}"/>
I've never actually tried this. Maybe I should before posting this, but I
don't know why it would work. I thought the EL only had access to bean
properties? So why would it be able to access a field directly?

do something like:request.setAttribute(foo.bar.attributeNames.BAZ, results) but
in JSPyou're not able to do the same thing?> But I don't know how to do this.
Anybody know how?> What, exactly, are you trying to do? You can access
anything on a JSPpage by <%@ page import="..."%>-ing it. You can access things
by puttingthem into scope. You can put strings
into a resource file and accessthem from both JSP and code, and you get
automagically I18Nized to
