Hi

I have been trying to get hibernate-osgi to work using container managed jpa in virgo (which IIRC is equinox based). However, I was not really successful in doing so.

First I tried combining hibernate-osgi with aries-jpa (the jpa21 branch https://github.com/brmeyer/aries/tree/jpa21, BTW its a major pain in the backside that this code does not compile on a mac with jdk7). While this should work I had problems where either hibernate-osgi or aries-jpa were hanging in starting state forever (without any meaningful error messages being printed out).
The next approach was to try and run hibernate-osgi together with gemini jpa, however, it seems that gemini-jpa only works with eclipse link (at least I did not figure out how to use it with hibernate-osgi).

So my questions are:
1. is there some recommended setup which is supposed to work (ideally a ready made example that I can deploy to a recent equinox)
2. is the jpa21 branch of aries-jpa really the only viable option for the aries route? This seems a quite laborious route in order to get this to work. It certainly does not have the "tutorial character" that most people are looking for.
3. are there other enterprise jpa containers that are supposed to work?

I read the thread https://forum.hibernate.org/viewtopic.php?f=1&t=1029974 where the original poster got hibernate working without using a container but building the EMF himself out of the PersistenceProvider. This would probably be an option but (AFAIK) requires some buddy class loading gymnastics etc which the managed jpa solution (IMHO) should avoid.

Any suggestions?

thanks

Integrating and testing with Equinox/Gemini, and providing a quickstart, is towards the top of my list. But, unfortunately, we've been swamped. We've fully tested with a Karaf/Felix & Aries JPA setup. And yes, it's definitely a pain to use that separate Aries branch, but the team will hopefully be pulling in the JPA 2.1 work in a soonish release.

You mention that my Aries fork doesn't compile -- what exactly are you seeing?

If you compile with JDK7 then the compilation will not work (some deprecated classes were removed). I had to switch to jdk6 to be able to compile it. Note that the java JVM version needs to be java6, not the maven compiler settings.

Sorry, forgot -- Apache Aries still requires JDK 6. Not idea about their plans to support 7.
