> The OSGi spec states (r4.2 127.3.1):
> "Entity Manager Factory service - Provides an EntityManagerFactory object that depends on a complete
> Persistence Unit. That is, it is associated with a registered Data Source Factory service."
> The current behaiviour is, that aries registers a Entity Manager Factory service regardles of the precence of a matching Data Source Factory service (Also see 127.5.3 Data Source Factory Service Matching).
> If no such matching is performed, it alternateively must register a Entity Manager Factory Builder service (not currently supported by Aries see ARIES-735 for reference).
> What infact is unclear to me is:
> 127.5.3 states that: "Once the Data Source Factory is obtained, the JPA Provider must obtain a DataSource object. This
> Data Source object must then be used for all relational database access."
> It does not state how this DataSource could be handed over to the PersistenceProvider for later usage.
> It might be suitable to insert a level of indirection here:
> - Aries just reads the persitence units and registers an Entity Manager Factory Builder service
> - PersistencProvider specific bundles match these with the required data source and register the Entity Manager Factory service
