how to test session variables

["Agrawal, Anuj (Anuj)** CTR **" <ag...@lucent.com>]

I'd like to use either the <when> or <if> tags to test for existence of a
session variable.

I tried:

<c:if test="$session.username != null">
	session.username is available
</cf:if>

But it didn't recognize $session.

I'm trying to replace the existing working code with JSTL tags:
<%
	if (session.getAttribute("username") != null) {
%>
	session.username is available
<%
	}
%>

Any pointers would be appreciated.
Thanks.
Anuj.

The syntax for this will depend on the final JSTL expression language.  
We hope that the upcoming beta release will contain a more final version,
so I'll hold off commenting for now on workarounds in the preliminary
(EA3) languages, if that's all right.  In a week, things should be closer
to their eventual form.
