With JSP 2.0 you can use EL in all the page because it is part of the
specification. Whit JSP 1.2 you can only use it with JSTL tags and customs
tags (this last one I'm not very sure). EL is evaluated before the JSP
is converted to a servlet, so I don't think you can use it in a servlet.
Here's a good link about the differences between JSP 1.2 and 2.0.

one of the respondents seemed to be implying you can only use EL with
JSTL, I don't suppose I understood right, since I assume it can also be
used with custom tags and beans..
again, thank you very much..

Behind the scenes JSPs are Servlets .
I had the same problem as maya is facing and after following the
instructions here:
http://wiki.apache.org/jakarta-taglibs/FrequentlyAskedQuestions , and
making sure that there was no version mismatch between the .tld files and
the URIs and getting the correct versions of the JAR files solved the
problem.

Expression Language (EL) is part of the JSP 2.0 specification. If I'm
not
wrong it has anything to do with servlets. If you use JSP 1.2 you have
to
import the JSTL libraries. I think that Tomcat 5 implemnts JSP 2.0.
Sorry my english.

I can't get my EL expressions to evaluate to what they're supposed
to...
they print verbatim, in both IE and FF, like for example:
Server Name: ${pageContext.request.serverName}
Server Port: ${pageContext.request.serverPort}
Remote Address: ${pageContext.request.remoteAddr}
Remote Host: ${pageContext.request.remoteHost}
or this in a bean:
Name retrieved from JavaBean has the value of: ${param.name}.
anything else I've tried to do w/EL it always prints like this in
browser.. why is this.. (running on Tomcat 5, everything pretty
standard..) thank you..
