Hi,
This sounds like a version compatibility problem.
Make sure you don't have the servlet/jsp/jstl jars in your applications web-inf/lib directory as they are provided by the server - this could cause this type of problem.
Otherwise post your
jsp and web.xml and we can see if anything else pops out.
Cheers!!!
