    Problem in PortletRequestDispatcher, please help me!

    rong zhai Newbie

      I use Java 1.5.0_06-b05, jboss Server 4.0.2 Portal 2.0.1RC.

      the portlet code:
      package oksimtk;

      import javax.portlet.*;
      import java.io.IOException;

      public class SearchPortlet extends GenericPortlet {
      protected void doView(RenderRequest request,RenderResponse response)
      throws PortletException, IOException {
      response.setContentType("text/html");
      PortletRequestDispatcher prd =
      getPortletContext().getRequestDispatcher("Search_view.jsp");
      prd.include(request, response);
      }
      }

      the jsp code:

      <%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
      <%
      String path = request.getContextPath();
      String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
      %>

      <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">




      My JSP 'Search_view.jsp' starting page

      <meta http-equiv="pragma" content="no-cache">
      <meta http-equiv="cache-control" content="no-cache">
      <meta http-equiv="expires" content="0">
      <meta http-equiv="keywords" content="keyword1,keyword2,keyword3">
      <meta http-equiv="description" content="This is my page">

      <!--

      -->



      This is my JSP page.



      I get a PortletException:
