I have a standalone component that consists of some EJB3 entities and statelss beans. How can I deploy this component to different Jboss systems which may have different data sources defined already? I assume this component does not bundle with its own database and data source and would like share with whatever data source available on the system. I tried to create EntityManagerFactory manually but no way to dynamic specify unit name or persistence provider. If use Persistence.xml way, the unit name and data source are static.
