org.apache.openejb.core.transaction.TransactionPolicy
TransactionPolicy represents a JEE container managed or bean manage transaction.
This class can be used to query the transaction status, set the transaction rollback only flag, associate resources with the transaction and to register a listener for transaction completion events.
