How to forward from a JAX-RS service to JSP?

JBoss Version: 4.2.3GA. This works in apache tomcat 6.0. In JBoss, I had to add the following setting: -Dorg.apache.catalina.STRICT_SERVLET_COMPLIANCE=false to get the forward to work, but now when I load the page I get the error below. It feels like I am doing this in a way JBoss doesn't like, but I haven't seen any other examples. Does anyone know a way to get this to work?

import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;

...


@GET
@Path("/forward")
public String forward(
    @Context final HttpServletRequest request,
    @Context final HttpServletResponse response) throws Exception
{
  RequestDispatcher dispatcher = request.getRequestDispatcher("/ind开发者_开发问答ex.html");
  dispatcher.forward(request, response);
  return "";
}

The exception:

After getting some help from another location, I realized that I was connecting my JSP and restlet in a funny way, and what I really wanted to do was use a Viewable. This also works way better in JBoss. Here is a summary of what I ended up with:

import javax.ws.rs.core.Context;
import javax.ws.rs.Path;
import javax.ws.rs.GET;
import com.sun.jersey.api.view.Viewable;


@GET
@Path("/index")
public Viewable index(
    @Context HttpServletRequest request,
    @Context HttpServletResponse response) throws Exception
{
  request.setAttribute("key", "value");
  return new Viewable("/jsps/someJsp.jsp", null);
}

If you are not using Jersey, you may want to do this:

@Path("")
@ApplicationPath("blog")
@Stateless
public class BlogApplication extends Application {

    @EJB private PostEJB postEJB;

    @GET
    public void getHome(@Context HttpServletRequest request, 
                        @Context HttpServletResponse response) {
        request.setAttribute("posts", postEJB.getPosts());
        request.getRequestDispatcher("/WEB-INF/pages/blog/home.jsp")
               .forward(request, response);
    }

    @Override
    public Set<Class<?>> getClasses() {
        return new HashSet<Class<?>>(Arrays.asList(BlogApplication.class));
    }

}
