Re: [eclipselink-users] Felix Karaf / No Persistence provider exception

(Oops I sent the message too quickly)

I'm not tied to Karaf. The point is it is a very good OSGi  
implementation, and provides the new Blueprint stuff. I will  
definitively not use any OSGi implementation witout Blueprint.

Hibernate is 0% OSGi. Running Hibernate is 100% hacking... the reason  
why I would like to migrate.

Thanks for the link!
