Including Servlets/JSPs in templates?

Hello, I need to be able to include a Servlet or JSP from inside of /templates/*.vm files (specifically header and footer). I tried things like: $request.getRequestDispatcher("/xxx.jsp").include( $request, $response ) But for some reason (buffering in Velocity I guess) it renders included page before anything else, no matter where it's actually placed. Is there some workaround? If not, I think I have an idea how to implement a kind of "#includeServlet" directive, could it be included in XWiki then? Greetings, Lilianne E. Blaze
