PostHeaderIcon XAException: JDBC driver does not support XA, hence cannot be a participant in two-phase commit

Error:

MyStrutsAction     - Error on uploading: MyPersonnalClass@971720[primaryId=<null>,type=XXX,myDate=20080702,entityId=<null>,optimisticTimestamp=<null>] org.springframework.remoting.RemoteAccessException: Could not access remote service [my-service-bean]; nested exception is javax.transaction.TransactionRolledbackException: BEA1-0F416BB49A8BE6353E83: javax.transaction.xa.XAException: JDBC driver does not support XA, hence cannot be a participant in two-phase commit. To force this participation, set the GlobalTransactionsProtocol attribute to LoggingLastResource (recommended) or EmulateTwoPhaseCommit for the Data Source = myDatasource

  • Then follow the pages: Home > Summary of JDBC Data Sources > myDatasource > Transactions
  • Uncheck:One-Phase Commit
  • Check: Emulate Two-Phase Commit
