And what would that configuration be?  It's tough to answer a question
without knowing what Tomcat level, what JRE/JDK, what OS, etc.  You're
asking people to guess.

Try using the admin app that is available for whatever Tomcat level
you're using.

Sounds like you should at least read the Servlet and JSP specs, which
are available on the Sun download site:
http://java.sun.com/products/servlet/download.html#specs
http://java.sun.com/products/jsp/download/index.html#specs

Upon first reference to the .jsp page.
