Environment: JBoss Portal Version: 2.6.3 Did you get Portal from CVS? or download it? --> download binaries JBoss AS Version --> 4.2.2.GA Database Vendor and Version --> Oracle 10g JDBC Connector and Version --> ojdbc14.jar OS Platform --> Windows XP
Problem/Question I know this has been posted before, but am unable to verify wether anybody has successfully implemented portlets based on Seam 2.0. Is there anybody out there who has made a simple working seam 2.0 portlet, and has starting with seam-gen? I did get the examples working (well, more or less: there are still serious issues like several links that don't work, but at least the portlet shows in the portal), following this blog entry: http://blog.jboss-portal.org/2007/11/seam-20-portlet-example.html But when I try to cook my own Seam 2.0 portlets I am getting all kinds of errors, the last one being: 17:07:04,530 ERROR [STDERR] Caused by: java.lang.ClassCastException: javax.portlet.faces.GenericFacesPortlet | 17:07:04,530 ERROR [STDERR] at org.jboss.portal.portlet.impl.jsr168.PortletContainerImpl.start(PortletContainerImpl.java:231) | 17:07:04,530 ERROR [STDERR] ... 74 more | 17:07:04,546 WARN [InstanceMetaData] The instance SimpleSeamPortletInstance will not be created because the component referenced is | outside of the same web app portlets06simpleSeam.SimpleSeamPortlet | 17:07:04,546 WARN [PortletAppDeployment] Failed to create instance SimpleSeamPortletInstance of portlet /portlets06simpleSeam.Simpl | eSeamPortlet because portlet /portlets06simpleSeam.SimpleSeamPortlet is not available (full stack trace pasted further down below).
