No, there's no guaranteed order (it can be different between transaction
instances and between commit phases). None of the standards provide for
it (going back beyond X/Open), and in fact that's one of the reasons
synchronizations were introduced as a separate protocol (to guarantee
ordering). So JTA or JTS won't help you here. However, if you want to
look at JBossTransactions specifics, then that can help you: we give you
full control over the ordering of participants.

One of you transaction gurus may know the answer:
If I enlist 2 (or more) XAResources into a JTA transaction.
Transaction tx = tm.getTransaction();
tx.enlistResource(res1);
tx.enlistResource(res2);
Then I rollback the transaction, which causes rollback() to be called
on each of the XAResources.
Are there any guarantees on the order in which rollback() is called on
the resources, or is this up to the transaction manager implementation?
E.g. is rollback always called in the same order the resources were
enlisted?
