Hi, I use some entity beans in my application. In wsad, if i bind normal oracle datasource which use oracle.jdbc.pool.OracleConnectionPoolDataSource as driver, everything is ok, only problem is transaction rollback not happen. I'm told that should use oraclexadatasource which use oracle.jdbc.xa.client.OracleXADataSource as driver, then always throw out sqlexeption said that parent key not found. Anyone know the reason and solution? Big thanks!
