RE: Pluto 1.1.4 - java.lang.InstantiationException while deploying

I followed the steps indicated by
a) http://www.ociweb.com/jnb/jnbAug2006.html
b) http://portals.apache.org/pluto/v11/deploying.html

Successfully created the war file with maven and deployed without errors

I still see the exception given below.

The URL given in (a) uses JetSpeed2. Do I need that too?

Thanks
Murthy

With the change done as suggested above the error now is:

SEVERE: Servlet.service() for servlet HelloWorld threw exception
java.lang.NullPointerException
        at org.apache.pluto.core.PortletServlet.dispatch(PortletServlet.java:196)
        at org.apache.pluto.core.PortletServlet.doGet(PortletServlet.java:145)

I think the exception in the dispatch is because the following session variables are not set:

javax.portlet.response
javax.portlet.request
org.apache.pluto.core.method

The relevant code from PortletServlet.java

// Retrieve attributes from the servlet request.
        Integer methodId = (Integer) request.getAttribute(
            Constants.METHOD_ID);

        portletRequest = (InternalPortletRequest) request.getAttribute(
            Constants.PORTLET_REQUEST);

        portletResponse = (InternalPortletResponse) request.getAttribute(
            Constants.PORTLET_RESPONSE);


I'd appreciate some more help. May be someone can post the web.xml that works!

Thanks
