With JSP 2.0 - EL can be used anywhere one a page. As an added bonus - you can pass expressions as values to your own custom tags and the container will translate the EL expression before the set...() of your tag is called.

From: Tim Funk Via EL: (assuming sessionData.FILECOUNT = mySessionVariableName)
${sessionContext.mySessionVariableName}
Via snippet:
<%=session.getAttribute(sessionData.FILECOUNT)%>
In a jsp - the session variable is given to you as implicit variable.
Thanks Tim ( and fstmncn ).
Hadn't come across 'EL'.
So the choice is one from 3?
JSP 1.0 rev B.
JSP (is it 1.2 or 2.0?) (XML syntax)
and Expression Language.
so what's JSTL, http://jakarta.apache.org/taglibs/doc/standard-doc/standard/GettingStarted.html ? <quote>JSTL encapsulates, as simple tags, core functionality common to many JSP applications.</quote> Is that the full name of the EL?
http://java.sun.com/products/jsp/jstl/1.1/docs/tlddocs/index.html seems to be the spec. Is there a reasonable tutorial anywhere please?
Can they be mixed in a page? I *think* the JSP version is determined by the vsn of Tomcat, which relates to the servlets version, but can I mix EL and JSP?
Is the relationship documented anywhere please?
