    deploy portlet to display applets failure

    hubery he Newbie

      What I want to do is try to deploy a portlet to display applets, I used the example "helloworldjspportlet" downloaded from jboss portletswap.

      My jboss portal version: GA2.6.6

      I both changed helloworldjspportlet.java and porlet.xml file as following:

      1, helloworldjspportlet.java

      package org.jboss.portlet.hello;

      import javax.portlet.ActionRequest;
      import javax.portlet.ActionResponse;
      import javax.portlet.GenericPortlet;
      import javax.portlet.PortletException;
      import javax.portlet.PortletRequestDispatcher;
      import javax.portlet.RenderRequest;
      import javax.portlet.RenderResponse;
      import javax.portlet.UnavailableException;
      import java.io.IOException;
      import java.applet.*;
      import java.awt.*;


      public class HelloWorldJSPPortlet extends GenericPortlet
      {
      protected void doView(RenderRequest rRequest, RenderResponse rResponse) throws PortletException, IOException, UnavailableException
      {
      rResponse.setContentType("text/html");

      String sYourName = (String) rRequest.getParameter("yourname");

      if(sYourName != null)
      {
      rRequest.setAttribute("yourname", sYourName);
      PortletRequestDispatcher prd = getPortletContext().getRequestDispatcher("/WEB-INF/jsp/view2.jsp");
      prd.include(rRequest, rResponse);
      }
      else
      {
      PortletRequestDispatcher prd = getPortletContext().getRequestDispatcher("/WEB-INF/jsp/view.jsp");
      prd.include(rRequest, rResponse);
      }
      }

      public void processAction(ActionRequest aRequest, ActionResponse aResponse) throws PortletException, IOException, UnavailableException
      {
      String sYourname = (String) aRequest.getParameter("yourname");

      // do something

      aResponse.setRenderParameter("yourname", sYourname);
      }

      protected void doHelp(RenderRequest rRequest, RenderResponse rResponse) throws PortletException, IOException, UnavailableException
      {
      rResponse.setContentType("application/x-java-serialized-object");
      PortletRequestDispatcher prd = getPortletContext().getRequestDispatcher("/WEB-INF/jsp/help.jsp");
      prd.include(rRequest, rResponse);
      }

      protected void doEdit(RenderRequest rRequest, RenderResponse rResponse) throws PortletException, IOException, UnavailableException
      {
      rResponse.setContentType("text/html");
      PortletRequestDispatcher prd = getPortletContext().getRequestDispatcher("/WEB-INF/jsp/edit.jsp");
      prd.include(rRequest, rResponse);
      }
      }

      accoring to the setContextType ,I have tried "application/x-java-applet" "application/x-java-serialized-object" ,both failed.

      2. portlet.xml file


      <portlet-name>HelloWorldJSPPortlet</portlet-name>
      <portlet-class>org.jboss.portlet.hello.HelloWorldJSPPortlet</portlet-class>

      <mime-type>application/x-java-applet</mime-type>
      <portlet-mode>VIEW</portlet-mode>
      <portlet-mode>EDIT</portlet-mode>
      <portlet-mode>HELP</portlet-mode>

      <portlet-info>
      HelloWorld JSP Portlet
      </portlet-info>

      </portlet-app>


      I have to say, the help.jsp in first file is a jsp which has applet inside.

      When I use ant deploy and ant explode to re-deploy this example portlet and put it under /default/deploy directory, it gave me this error:

      ------ just a piece , from the error, it is not difficult to understand it is the

      context type problem, but how to fix it ,anybody can give me a hand?

      Thanks!
