Hi,
I think there is a bug in Pluto Implementataion which throws up an exception
like this, if the web.xml doesn't contain any servlets or any other servlet
definition.
The Code in PortletInvokerImpl.java
javax.servlet.RequestDispatcher dispatcher =
servletDefinition.getRequestDispatcher(servletContext);
If the dispatcher is null ....... it throws a NullPointerException.
java.lang.NullPointerException

I can't think of anything else .......all my portlets which don't have a
web.xml definiton of a servlet throws this exception.
