I've installed JBoss 3.0.3, Tyrex 1.0, and Oracle 9.2. Using local transactions, everything runs fine. Using XATransactions however, I always get an XAException (-6) here:

oracle.jdbc.xa.OracleXAResource.disallowLocalTxnMode(OracleXAResource.java:1045)

As I've done a lot of guessing and trial and error in order to make things work, there's a fair chance that this is due to some configuration error. If someone happen to have a valid configuration for Oracle XA with Tyrex running in JBoss 3.0.3, I would be very greatful if you could post it on this forum.

Any advice is also greatly appreciated.

Thanks.
