Yes, 'javax.servlet.jsp.jspException' is the parameter
name that's used when the exception value is set.
It's important to know, because if you do MVC-2 with
your own front controller servlet you've got to set
that parameter inside the servlet whenever an
exception is thrown. If you don't, the JSP error page
won't find it.
Buy Shawn Bayern's "JSTL In Action" book by Manning.
What you wanted was right there on page 267. Lots of
other good stuff, too.
Anytime I'm faced with a new technology I like to have
a good book at my elbow. When I started with JSTL,
this was the only book I bought.
