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!
