Anybody got seam 2.0 portlets working?
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).
