RE: [JBoss-user] castor and transactions

[Dominik B. <dba...@sa...>]

thanks for the replies, guys.

In fact I threw a RemoteException instead, it caused a rollback. Everything
works great.

In fact it works so well that I'm wondering why even use entities in the
first place =)
I guess they might be useful if numerous apps are accessing the db.

I think the real reason that behavior is in the spec is that if the
application is throwing an application defined exception, really only
the application _can_ know whether or not to roll back. Not that I
wasn't surprised by the behavior...
