If you edit conf/context.xml and add crossContext="true", one Tomcat mounted web-app should be able to forward to (or include content from) another in the same request.
I can't get it working and I have a minimal Github project ( https://github.com/paul-hammant/servletDispatcherTest) that shows how far I got. It has 'a' and 'b' as web-apps (war files) and simple five line servlets showing the code, attempting to use // in 'a' webapp servlet filter ... ServletContext context = httpsr.getSession().getServletContext().getContext("/b"); RequestDispatcher requestDispatcher = context.getRequestDispatcher("/anything"); requestDispatcher.include(request, response); // gives .. The requested resource (/b/anything) is not available // If it were not for crossContext="true", there would be a n NPE. I'm looking for a whole example of this working. I mean a downloadable and buildable zip of a project somewhere on the web. Obviously I've tried google searching for that. I've also looked in Tomcat's source and can't see and example or integration test for crossContext :-( - Paul
