Failure in Deploying the Simplest of Portlets

[elam]

Hi all,

I'm simply trying to print a 'hello world'.

After my war file is dropped into the deployment directory, in the management portlet, under instances it always says "Portlet not deployed".

Can someone tell me what I'm doing wrong, please?

Here's my war file structure: - test2.war

WEB-INF:
 classes
 Test2.class
 jboss-app.xml
 jboss-web.xml
 portal.xml
 test2-object.xml
 web.xml

And the individual code for each file:

Test2.class:

mport java.io.PrintWriter;
import java.io.IOException;

import javax.portlet.GenericPortlet;
import javax.portlet.RenderRequest;
import javax.portlet.RenderResponse;
import javax.portlet.PortletException;

public class Test2 extends GenericPortlet {
 /**
 * The portlet's main view prints "Hello, World"
 */

 public void doView(RenderRequest request, RenderResponse response)
 throws PortletException, IOException

 {
 response.setContentType("text/html");
 PrintWriter out = response.getWriter();

 out.println("Hello, World");
 }

 public void render(RenderRequest rRequest, RenderResponse rResponse) throws javax.portlet.PortletException, IOException
 {
 rResponse.setTitle(getTitle(rRequest));
 doDispatch(rRequest, rResponse);
 }

}

jboss-app.xml

<?xml version="1.0" encoding="UTF-8"?>
<jboss-app>
 <app-name>Test2</app-name>

A little progress:

If I click on management -> portal -> root -> default and then 'add page' and then add an instance of my Test2 portlet to the newly added page, I get in red 'validation error' and search for that term turns up nothing.

Ah, I found the JIRA report for the 'validation error' message, so I've now added an instance of my portlet to my newly created page, but nothing is displaying in the tab, just blank.

This *must* be something simple.

I think that you must rename portal.xml in portlet.xml (it is required).

...and in your portlet.xml portlet class should be :

...
 <portlet-class>Test2</portlet-class>
...
