When i use hibernate3 final version this error occurs, but when i use the hibernate3-rc1 this error does not appear, but the container hangs.

And the rc1 version does not have CMTTransactionFactory, and like i read in documentation, this is the class that i need to use with ejb session bean!

Thanks for att.

Thanks for letting us know, but I think Gavin is right to a certain extend. We do not know everything. Certainly not if there is an issue in some code we cannot see. You can see in other posts that once we have a clue we certainly try to help (and in my situation, in my free, non payed time)

please bear with us.

In fact Ronald means 'beer to us', he just wants to be rewarded with a pint of nice and cold trappist beer...
No just kidding, the expression means that you'll have to live with our inevitable shortcomings... We don't know everything and have not always the time to investigate everything ;-)

P.S. We nevertheless like the way guys like you participate in forums and provide answers for their own problems. It is essential for others to learn something when they search these forums.
