Martin,
That worked, but I only see the first line of the stacktrace. Anyway to get

This is what I currently have:
<c:out value="${requestScope['javax.servlet.error.exception']}" />
Thanks,
jb

Hey Jeff,
The exception is available as a parameter in the request attributes
under "javax.servlet.error.exception".
