Re: XA capable driver

If it was a DB problem, why would JBossMQ (the JBoss JMS
implementation) be the one throwing an exception? In a 2-phase commit
session, you first prepare all the resources (DB & MQ), then if that all
works, you commit. Here the prepare on the MQ fails -- there's no error
from the DB. You need to find out why the SpyMQResource is failing to
prepare on line 169. I think XAER_RMERR is a generic "Resource Manager
Error" message, so it's not obvious what is causing it. Also it happens
at the end of the TX, which is why it manifests "after the method has
fully completed".
In any case, since there are no database errors below, please
reply off-list.
