 Description  « Hide
Currently we're limited to exploded deployments for initialization scanning of entity classes.
It should be possible to pass-in some-sort of Scanner instance from container / env, which would know how to do this better, more optimized.

Where JPAEntityManagerFactory:750 (in api.jpa) needs to be changed to use this new over-loaded method:
* nucleusCtx.getMetaDataManager().loadPersistenceUnit(unitMetaData, null, props);

SVN trunk now has an adaptation of your patch, thanks.
I've changed the following :-
* scanner interface is now MetaDataScanner
* scanner interface has method scanForPersistableClasses(...)
* no need to pass in properties into MetaDataManager method call since it has "nucleusContext" which provides access to all persistence properties.
