如何从JAX-RS服务转发到JSP？

Question

JBoss版本：4.2.3GA。这在apache tomcat
6.0中有效。在JBoss中，我必须添加以下设置：-Dorg.apache.catalina.STRICT_SERVLET_COMPLIANCE=false要继续工作，但是现在当我加载页面时，出现以下错误。感觉我正在以JBoss不喜欢的方式执行此操作，但是我还没有看到其他示例。有谁知道让它正常工作的方法？

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("/index.html");
  dispatcher.forward(request, response);
  return "";
}

例外：

从另一个位置获得帮助后，我意识到我正在以一种有趣的方式连接我的JSP和restlet，而我真正想做的就是使用Viewable。这在JBoss中也更好。这是我最后得到的摘要：

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);
}
