    JBoss Portlet throws ServletException

    jmckee Newbie

      I'm having a problem deploying a Portlet on JBoss Portal (2.0 alpha). I was attempting to create a hello world portlet as a starting point. It deplys fine but throws the following exception when I call it. Can anyone give me a few hints as to what is likely to cause this exception. I've attached the relevant section of the log.

          Managed to fix this myself and thought I'd post in case, like myself, any of the nukes community are experimenting with JBP.

          I had configured the root context incorrectly. In *-pages.xml the the /portal-hello part of the instance-ref (shown below) has to match the context configured in your .war file.

          <instance-ref>/portal-hello.HelloWorldPortlet.HelloWorldPortletInstance</instance-ref>

          Hope this helps someone
