RE: jsp version of session variable access. Pointer to syntax wanted.
-Original Message-
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
?
quoteJSTL 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?
regards DaveP

Re: jsp version of session variable access. Pointer to syntax wanted.
EL first arrives as part of JSTL. Which was available in JSP 1.2. But using
EL required that is was used in a tag.
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.

The JSP examples from a default tomcat install might have some. -Tim Pawson, David wrote: -Original Message- From: Tim Funk EL first arrives as part of JSTL. Which was available in JSP 1.2.

Re: jsp version of session variable access. Pointer to syntax wanted.
you can use expression language:
e.g.:
${sessionData.FILECOUNT}

I'm not using the xml syntax (as yet).
tomcat 5028.
any pointers appreciated please.
