If you use Eclipselink as a provider, then it's definitely possible to
export EMF as a service from one bundle and use it from other bundles.
See section #8 of [1]. You can also find examples of the same at [2] &
[3]. [2] exports EMF as a service and [3] consumes the service. I don't
know how you have got Hibernate working from your OSGi bundles, but if
you can create an EMF and export it as a service, then you can consume
it other bundles as a service.
