[jboss-user] [JBoss Messaging Users] - Re: Weird transaction error

[Ovi]

I had the same problem which on my side was caused by accessing 2 different data-sources within the same transaction (XA transaction on Oracle database).

E.g. Method X is calling method Y which does an database A insert and calls method Z which does a database B update.

The solution was to annotate method Y and method Z with: @TransactionAttribute(TransactionAttributeType.REQUIRES_NEW)

Hope this helps.
