如何从JAX-RS服务转发到JSP？

Question

JBoss版本:4.2.3GA.这适用于apache tomcat 6.0.在JBoss中,我不得不添加以下设置:-Dorg.apache.catalina.STRICT_SERVLET_COMPLIANCE=false为了使前进工作,但现在当我加载页面时,我得到以下错误.感觉就像我这样做是以JBoss不喜欢的方式,但我还没有看到任何其他的例子.有谁知道让这个工作的方法？

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:

在从另一个位置获得一些帮助之后,我意识到我正在以一种有趣的方式连接我的JSP和restlet,而我真正想要做的就是使用Viewable.这在JBoss中也更好用.以下是我最终得到的摘要:

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);
}
