I am trying to dispatch in a servlet request handler to the JSP processor and capture the content of it.

I am providing wrapper instances for the ServletRequest and ServletResponse, they implement the corresponding HTTPServletRequest/-Response interfaces, so they should be drop-in replacements. All methods are currently passed to the original Servlet Request object (I am planning to modify some of them soon). Additionally I have introduced some new methods. (If you want to see the code: http://code.google.com/p/gloudy/source/browse/trunk/gloudyPortal/src/java/org/gloudy/gloudlet/impl/RenderResponseImpl.java)

The HttpServletResponse uses it's own output streams to capture the output.

When I try to call

request.getRequestDispatcher("/WEB-INF/views/test.jsp").include(request, response);    

With my request and response wrappers the method returns and no content has been captured. When I tried to pass the original request object it worked! But that's not what I need in the long run...

request.getRequestDispatcher("/WEB-INF/views/test.jsp").include(request.getServletRequest(), response);

This works. getservletRequest() returns the original Request, given by the servlet container.

Does anyone know why this is not working with my wrappers?
