New issue 621 by [email protected]: ServeltContext#getRequestDispatcher
cannot forward to Guice Servlets
http://code.google.com/p/google-guice/issues/detail?id=621
Here is the simplest test case (I'm using tomcat 5.5.33):
* Use Guice ServletModule to configure two servlets, one of which just
dispatches to the other:
protected void configureServlets()
{
serve( "/dispatcher" ).with( DispatcherServlet.class );
serve( "/dispatchee" ).with( DispatcheeServlet.class );
}
* Dispatchee outputs text for verification, dispatcher redirects like this:
protected void doGet( HttpServletRequest req, HttpServletResponse
resp )
throws ServletException, IOException
{
this.getServletContext().getRequestDispatcher( "/dispatchee" )
.forward( req, resp );
}
* Invoking /dispatcher yields a blank page with a 404 status that is
incorrectly served up by Tomcat's default servlet.
* When configuring via traditional web.xml instead of guice, everything
works as expected.
* I did some debugging and it looks like Tomcat's internal pattern matching
inside its RequestDispatcher implementation isn't even aware of the servlet
mapping that Guice configured.
To fix it sounds like Guice will have to wrap the RequestDispatcher object
returned from ServletContext to route requests appropriately (see
discussion on issue 372).
