Re: JSP 2.0 and JSTL EL

Dick,

What Servlet and JSP specification version is JBoss 4.0.5 based on?

The compatibility chart for EL and web.xml I've known from experience is:
---------------------------------------------------------------------------------------------------------------------
JSTL 1.2      works with Servlet 2.5/ JSP 2.1 which is the spec for Tomcat 6.0.x
----------------------------------------------------------------------------------------------------------------------
JSTL 1.1.x   works with Servlet 2.4/ JSP 2.0 which is the spec for Tomcat 5.5.x
----------------------------------------------------------------------------------------------------------------------
JSTL 1.0      works with Servlet 2.3/ JSP 1.2 which is the spec for Tomcat 4.1.x
---------------------------------------------------------------------------------------------------------------------

the web.xml web-app / DTD / Schema are different for each of the above
versions of the Servlet spec.

Tomcat has a useful reference chart
http://tomcat.apache.org/whichversion.html which shows which version
of Tomcat uses which version of the Servlet spec, but I couldn't find
such a chart (after some searching) for JBoss.

-Regards
Rashmi
