When you grabbed the postgresql-persistence-service.xml, you probably looked over the comments near teh bottom that say "All the remaining properties only have to be specified if the post office is clustered. You can safely comment them out if your post office is non clustered" You need to comment out: attribute name="GroupName" attribute name="StateTimeout" attribute name="CastTimeout" attribute name="FailoverOnNodeLeave" depends optional-attribute-name="ChannelFactoryName" attribute name="ControlChannelName" attribute name="DataChannelName" attribute name="ChannelPartitionName" That will get rid of the error messages like: NOT FOUND Depends on 'jboss.jgroups:service=ChannelFactory' View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4202290#...
