Anyone? I checked SVN but only seems to be a 2.4 version of the IPC portlet. No 2.2. I don't see any options in the build file to make a 2.2 version either. The error I'm getting is: (bottom of stack trace) | 16:35:10,577 WARN [ServiceController] Problem starting service portal:service=ListenerService,type=ipc_listener | java.lang.ClassCastException: org.jboss.portlet.hello.HelloWorldPortletB$Listener | at org.jboss.portal.core.event.PortalEventListenerServiceImpl.startService(PortalEventListenerServiceImpl.java:101) at org.jboss.system.ServiceMBeanSupport.jbossInternalStart(ServiceMBeanSupport.java:274) | at org.jboss.system.ServiceMBeanSupport.start(ServiceMBeanSupport.java:181) | at org.jboss.portal.common.system.AbstractJBossService.start(AbstractJBossService.java:86) | at sun.reflect.GeneratedMethodAccessor18.invoke(Unknown Source) | at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) | Then at the end of the console file: | 16:39:41,281 ERROR [URLDeploymentScanner] Incomplete Deployment listing: | | --- MBeans waiting for other MBeans --- | ObjectName: portal:service=ListenerService,type=ipc_listener | State: FAILED | Reason: java.lang.ClassCastException: org.jboss.portlet.hello.HelloWorldPortletB$Listener | I Depend On: | portal:service=ListenerRegistry | | --- MBEANS THAT ARE THE ROOT CAUSE OF THE PROBLEM --- | ObjectName: portal:service=ListenerService,type=ipc_listener | State: FAILED | Reason: java.lang.ClassCastException: org.jboss.portlet.hello.HelloWorldPortletB$Listener | I Depend On: | portal:service=ListenerRegistry | View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3974376#...
