extending EntityManager

[Heather Sterling <vt...@gmail.com>]

Hi,

I'm looking to extend OpenJPA's entity manager to provide some additional
methods.  Based on my reading, it seems like I can extend both the default
EntityManagerFactory and the default EntityManager.  However, I can't seem
to find any information on how to actually do this. Any pointers are
appreciated.

Thanks,
Heather Sterling

Hi,
  Take a peek at openjpa-slice. This module extends both north-bound and
south-bound APIs i.e. EntityManager and StoreManager for core OpenJPA object
management kernel.

Heather,
Yes, the EMF and EM implementations can be extended.  There's nothing
preventing that, but this makes it sound like you might be interested in
providing your own flavor of OpenJPA as a Persistence Provider.  This is
also doable, but this might be more work than you think.  Can I ask why you
want to do this?  There might be alternative ways of accomplishing the same
thing without as much effort.
