I'm using Jboss3.2.3, Oracle9i and JbuilderX Enterprise

Hello all. Does anyone know what driver I should use for 2pc?
I tried the config below and it doesn't work. I get no errors but when the insert is part of a UserTransaction it just doesn't commit with txn.commit() but I can do a select statement and I get all the data back.

<xa-datasource-class>oracle.jdbc.xa.client.OracleXADataSource</xa-datasource-class>
<xa-datasource-property name="URL">jdbc:oracle:thin:@localhost:1521:estate1</xa-datasource-property>



do I have to implicitly enlist each resource into the transaction or does this happen automatically when the datasource is bound to jboss?
