I'm trying to include a servlet inside a jsp and the action is resulting
in a weird error message. I've tried both:

<jsp:include page="/servlet/TestServlet" flush="true" /> and <img
src="/servlet/TestServlet" width="XXX" height="YYY" />

to no avail. The resulting error when the servlet is called is as
follows:
