If you are getting the error (or similar):
Chances are the problem is one of:
You forgot to put the JSTL jar files (there are usually two) in WEB-INF/lib.You are using the wrong URI (such as the outdated: http://java.sun.com/jstl/core).You tried to declare it in web.xml, which is no longer necessary, and that's fouling things up.
