I am trying to deploy a JSR286 portlet, but get the following exception.

14:21:28,902 ERROR [LifeCycle] Cannot start object
org.jboss.portal.portlet.container.PortletInitializationException: The portlet Event Publishing Example Portlet threw a runtime exception during init
at org.jboss.portal.portlet.impl.jsr168.PortletContainerImpl.start(PortletContainerImpl.java:288)
at org.jboss.portal.portlet.impl.container.PortletContainerLifeCycle.invokeStart(PortletContainerLifeCycle.java:76)
at org.jboss.portal.portlet.impl.container.LifeCycle.managedStart(LifeCycle.java:92)


looks like it thinks that the portlet is jsr 168..... why??
