Do you mean, if you want to deploy your application with just the admininstration module, then only the entities belonging to administration module be mapped? The entities that are deployed is based on the contents of (1) application.xml file (present int the META-INF of your EAR) (2) the contents of the persistence.xml file. You can disable the deployment of a module, by removing it entry from the application.xml View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4157352#...
