hi there, There is also an easy way to get the HelloWorldIPC sample for Jboss Portal 2.2.0 with Jboss Portal 2.2.1SP3: Simply download the sample file for Jboss-Portal 2.2.0: http://labs.jboss.com/file-access/default/members/portletswap/downloads/p... and then replace the portlet-related libraries in the lib-directory (portlet*.jar, portal*.jar) with the libraries of jboss-portal-2.2.1-SP3-bundled\server\default\deploy\jboss-portal.sar\lib\. run ant clean / ant and then it works like a charm. regards, johannes View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3990793#...
