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.
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. -Tim Pawson, David wrote: -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 ? JSTL encapsulates, as simple tags, core functionality common to many JSP applications. 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 - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

you can use expression language: e.g.: ${sessionData.FILECOUNT} --- "Pawson, David" <[EMAIL PROTECTED]> wrote: > Looking for the syntax to gain access to a session > variable > in a jsp page, rather than converting it to java. > > HttpSession session=request.getSession(); > String s = > (String)session.getAttribute(sessionData.FILECOUNT); > > I'm not using the xml syntax (as yet). > tomcat 5028. > > any pointers appreciated please. > > Regards DaveP. > > snip here * > > -- > DISCLAIMER: > > NOTICE: The information contained in this email and > any attachments is > confidential and may be privileged.
