RE: Setting up JSTL---How?
One step you need to take care of, if you haven't yet, is reading the
JSTL specification. If you had, you would have noticed that
$param.userName should be ${param.userName}. I'm not certain
whether this the cause of your exception, however.

here is my test.jsp :
!--
%@ taglib prefix=c uri=http://java.sun.com/jstl/core;

Your name is : c:out value=$param.userName
default=Unknown /

when i ran it, errors happened. this is the error:
