Erm,
Not really experienced enough with JSTL yet for that. What you're currently getting is
the exception.toString(). For the full stacktrace you'd need to do:
<%
((Exception)request.getAttribute("javax.servlet.error.exception")).printStackTrace(response.getWriter());
%>
How to express that in JSTL, I don't know. I'd specifically not know whether the cast
was necessary and how to pass the printStackTrace method the PrintWriter.
