If I reduce my webapp down to just this:

> <%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>


Then I get:

But the standard.jar I'm using is the SAME one from Tomcat 5.5 and even 
the md5sum is the same (so its not corrupt).

The insane parse is that everytime I reload the page I get a diff error 
(FUN!)

BTW. Throughout this ENTIRE process Tomcat has been swallowing the real 
error. Not very professional :-/ Makes me wonder what other fun little 
secrets Tomcat has in store for me in the future.
