It looks like your web.xml is incorrect.
For Pluto 1.1, you need to have <load-on-startup> (which you have
commented out), the <init-param> portlet-name (check), and you need a
<servlet-mapping> "HelloWorld" to "/PlutoInvoker/HelloWorld/" (which you
don't have at all).
The other elements in your web.xml (portlet-guid, portlet-class) are for
Pluto 1.0. Which are fine to keep in your web.xml if you are planning
to deploy the portlet in multiple container.
I think the existing servlet mapping you have is incorrect for both
pluto 1.1 and pluto 1.0 containers.
As an aside, your web.xml contains a doctype for servlet 2.3, but your
<web-app> and following is in the servlet 2.4 namespace. That may
confuse things as well. Tomcat is probably forgiving but other servlet
containers may not be.

Hi
I am testing a HelloWorld app. Here is the HelloWorld.java
package testpluto;
import javax.portlet.GenericPortlet;
import javax.portlet.RenderRequest;
import javax.portlet.RenderResponse;
import javax.portlet.PortletException;
import java.io.IOException;
import javax.servlet.*;
public class HelloWorld extends GenericPortlet {
protected void doView(RenderRequest request,
RenderResponse response) throws
PortletException, IOException {
response.setContentType("text/html");
response.getWriter().println("Hello Portlet");
}
}
I have successfully compiled this class and

I have been breaking my head over these for nearly 40 hours now.
Sorry, I don't know maven and don't intend to know at this time. I am fine with
ant.
It took me a while to understand the deploy. I even tried deploying from the
manager/admin screens. Still
The same result.
I'd appreciate all of the help you can give me in making this successful.
Thanks
Murthy
