Right Ozgur, once again Ive misunderstand the question. Glad I don't work in
support, it would be a disaster.
So we are talking about including a servlet (or JSP) from the same servlet

In that case, ignore my response, thats for getting content outside of your
servlet container.
Take a look at the ServletInvokerPortlet
