| javax.transaction.TransactionManager
| TransactionManager | | public interface TransactionManager (Code) | | The TransactionManager interface defines the methods that allow an
application server to manage transactions on behalf of the applications.
User applications should not use this interface directly, but use
UserTransaction insted if they need to do their own transaction
management.
Internally, the transaction manager associates transactions with threads,
and the methods here operate on the transaction associated with the
calling thread.
