Error while dispatching portlet

[Markus Wachowski <Ma...@businessobjects.com>]

Hi

when I try to view my portlet, instead of my content ("Hello World"),
I'm getting "Error occurred in portlet!".  In the Tomcat console I'm 
getting the following errors.


    Feb 23, 2004 11:13:36 AM
org.apache.pluto.portalImpl.services.log.LoggerImpl info
    INFO: Initializing PortletContainer [pluto]...
    Feb 23, 2004 11:13:40 AM
org.apache.pluto.portalImpl.services.log.LoggerImpl error
    SEVERE: PortletInvokerImpl.render() - Error while dispatching portlet.
    Feb 23, 2004 11:13:40 AM

Since this is a just a Hello World portlet, I think I must have some
beginner's error in one of my .xml files.
Any suggestions would be welcome

thanks
Markus
