[jboss-user] [EJB 3.0] - Re: Persistence unit scoping across multiple jars in a singl

anonymous wrote : | A persistence unit must have a name. Only one persistence unit of any given name may be defined within a single EJB-JAR file, within a single WAR file, within a single application client jar, or within an EAR (in the EAR root or lib directory). | And as for scope of the persistence.xml (between EJB, WEB, or EAR) anonymous wrote : | A persistence unit that is defined at the level of the EAR is generally visible to all components in the application. | So if you put your generic persistence.xml in the root folder(where your EAR is defined or in a lib subfolder), all your sub deployments should be able to use that.
