Hi -

Good job on the new release. Question, where in the documentation can I find reference to do the new seamless J2EE/JTA container integration of Hibernate sessions?

Thanks!

Well its not just one thing...

Check out documentation for:
1) auto_close_session
2) flush_before_completion
3) SessionFactory.getCurrentSession()

Or check out http://blog.hibernate.org/cgi-bin/blosxom.cgi/Steve%20Ebersole/current-session.html which discusses these...

Awesome, thanks for the quick reply.

Wow, I just implemented those changes - this is awesome.

Good job!

It seems me to have had problems when I keyed the map by JTA transaction (javax.transaction.Transaction Object).
I then used the identifiers of the transaction (XID object) for the key in order to resole the problem.

Have I wrong or right ?

XIDs are not available via a javax.transaction.Transaction.

By spec, a cntainer is supposed to provider appropriate equals/hashCodes for their javax.transaction.Transaction implementations. Now if your container does not do that, then you might have problems depending upon how the TM is implemented.

The methods equals and hashcode have been coded with the XID by my provider. This explains why i use the XID for the key of my map.
Thanks

This doesn't explain why i have had a problem ...
In fact, I don't know any more why I had this problem

An other problem
...if the method getCurrentSession is called in a "no-required transaction" method (method call with no transaction JTA), an exception is raised by this class SessionFactory .
If a test on the existence of the transaction is made and if in the case where there is no transaction, we return a simple session (not put in the map), this mechanism is a solution ?

Hello,

is it necessary to have a TransactionManagerLookupClass if I want to use the currentSession() method? We need to support the Sun ApplicationServer Version 8 and I think that in this Release it is not possible to get the TransactionManager via JNDI Lookup (due to the fact that this is not specified in the J2EE spec). Or should we use a JCA Connector for Hibernate, which seams to be not finished and documented yet for Hibernate 3?

Kind regards

Alexander
