Hi Armin,

You are right there is currently no JTA integration !

I'm quite intereted in your implementation! Would you share your code? This
can be interesting for many users.

We definitely want to have JTA and JCA integration for OJB. Thus we
interested in all contributions in this direction.

Thanks,
