I've been moving along developing portlets using 2.6.2, no problems. All of a sudden I'm getting a class cast exception. I haven't added any jars to the server or to my project. I've even tried copying the portlet jars from the portlal.sar/lib and adding them to my project as a fix, still no luck. Can anyone give a recommendation as to what to try? I've reinstalled a fresh copy of the 2.6.2 bundled with AS, didn't help. I know it must be a jar conflict somewhere, just can't seem to figure out where. Is it the "portal-portlet-jsr168api-lib.jar" or "portlet-api-lib.jar" files that could be causing this? Code that throws the exception: PortletRequestDispatcher prd = getPortletContext().getRequestDispatcher("/WEB-INF/jsp/view.jsp); prd.include(rRequest, rResponse); 21:08:27,996 ERROR [[jsp]] Servlet.service() for servlet jsp threw exception java.lang.ClassCastException: org.jboss.portal.portlet.impl.jsr168.api.PortletConfigImpl Thanks for any help.
