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.

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.

Maps are treated differently than regular JavaBeans so that you can't access
bean properties. For example, every object has a bean property called class,
but you won't get any output if you try ${map.class}. It's even more fun to try
and get at a map's empty property ;-). If all you're concerned

Right, because the wrapper would be a JavaBean, not a Map. The gory details
behind the . operator can be found in section A.3.4 Operators [] and . of
the JSTL 1.0 Spec.
Quoting Roy Benjamin [EMAIL PROTECTED]:

Roy, if you are using JSP 2.0 (e.g. with Tomcat 5) and JSTL 1.1 you can
do the following:

%@ taglib uri=http://java.sun.com/jsp/jstl/functions; prefix=fn %

Personally, I'd keep JSTL/Standard in WEB-INF/lib and Xerces/Xalan in endorsed.
Unless I needed an app-specific version of the XML libs, in which case I'd need
them in WEB-INF/lib. I wouldn't recommend dumping everything in endorsed, or
some other directory that a shared classloader can access,
el has been incorporated into JSP 2.0 which is what Tomcat 5 implements.
So, you no longer need the c:out tag. Just do:
p1 + 2 + 3 = ${1+2+3}/p
Check out Tomcat's default pages to see more cool things you can do with
Tomcat 5 (JSP 2.0/Servlet2.4).

From what little I know, JSP 2.0 introduces the concept of functions to

JSP 2.0 provides tag-library developers with the ability to expose static

This facility also allows JSTL to expose a set of standard functions.

My goal is to not change the existing library at all, either at the
source level or the deployment level. If you put the new classes in the
old jar, then people deploying the old taglib will get those extra

There is that, but in terms of project management for the Jakarta Taglibs,
it'll turn each ELized version into a new project, or a branch or
