I'm assuming that you're writing a servlet filter with a hook: That would intercept the full request, before the portal page is composed. If the JSP you want to render is part of a portlet, this will be a mismatch. Also, you might run into classloader issues - the servlet filter and the JSP might be running in different contexts. This is not easy or trivial in portal contexts. You should limit yourself to the portlet world with Liferay and stay away from servlets, servlet filters etc. for anything UI oriented. Liferay uses them for example for implementing single sign on systems - inherently non-UI components. But not for rendering a bit of UI - you should do the same.

Whatever you're trying to do: Let us know of the underlying problem and we might be able to come up with a suggestion.
