So this documentation seems to indicate that I can reference the entity manager from separate applications if it is configured in the global jndi namespace. http://docs.jboss.org/ejb3/app-server/reference/build/reference/en/html/e... This is done by adding these properties to persistence.xml | <property name="jboss.entity.manager.jndi.name" value="java:/Manager1"/> | <property name="jboss.entity.manager.factory.jndi.name" value="java:/Manager1Factory"/> | Am I on the right track here?
