Methods Summary
public void	begin() Create a new transaction and associate it with the current thread. exception NotSupportedException Thrown if the thread is already associated with a transaction and the Transaction Manager implementation does not support nested transactions. exception SystemException Thrown if the transaction manager encounters an unexpected error condition.
public void	commit() Complete the transaction associated with the current thread. When this method completes, the thread is no longer associated with a transaction. exception RollbackException Thrown to indicate that the transaction has been rolled back rather than committed. exception HeuristicMixedException Thrown to indicate that a heuristic decision was made and that some relevant updates have been committed while others have been rolled back. exception HeuristicRollbackException Thrown to indicate that a heuristic decision was made and that all relevant updates have been rolled back. exception SecurityException Thrown to indicate that the thread is not allowed to commit the transaction. exception IllegalStateException Thrown if the current thread is not associated with a transaction. exception SystemException Thrown if the transaction manager encounters an unexpected error condition.
public int	getStatus() Obtain the status of the transaction associated with the current thread. return The transaction status. If no transaction is associated with the current thread, this method returns the Status.NoTransaction value. exception SystemException Thrown if the transaction manager encounters an unexpected error condition.
public javax.transaction.Transaction	getTransaction() Get the transaction object that represents the transaction context of the calling thread. return the Transaction object representing the transaction associated with the calling thread. exception SystemException Thrown if the transaction manager encounters an unexpected error condition.
public void	resume(javax.transaction.Transaction tobj) Resume the transaction context association of the calling thread with the transaction represented by the supplied Transaction object. When this method returns, the calling thread is associated with the transaction context specified. param tobj The Transaction object that represents the transaction to be resumed. exception InvalidTransactionException Thrown if the parameter transaction object contains an invalid transaction. exception IllegalStateException Thrown if the thread is already associated with another transaction. exception SystemException Thrown if the transaction manager encounters an unexpected error condition.
public void	rollback() Roll back the transaction associated with the current thread. When this method completes, the thread is no longer associated with a transaction. exception SecurityException Thrown to indicate that the thread is not allowed to roll back the transaction. exception IllegalStateException Thrown if the current thread is not associated with a transaction. exception SystemException Thrown if the transaction manager encounters an unexpected error condition.
public void	setRollbackOnly() Modify the transaction associated with the current thread such that the only possible outcome of the transaction is to roll back the transaction. exception IllegalStateException Thrown if the current thread is not associated with a transaction. exception SystemException Thrown if the transaction manager encounters an unexpected error condition.
public void	setTransactionTimeout(int seconds) Modify the timeout value that is associated with transactions started by the current thread with the begin method. If an application has not called this method, the transaction service uses some default value for the transaction timeout. param seconds The value of the timeout in seconds. If the value is zero, the transaction service restores the default value. If the value is negative a SystemException is thrown. exception SystemException Thrown if the transaction manager encounters an unexpected error condition.
public javax.transaction.Transaction	suspend() Suspend the transaction currently associated with the calling thread and return a Transaction object that represents the transaction context being suspended. If the calling thread is not associated with a transaction, the method returns a null object reference. When this method returns, the calling thread is not associated with a transaction. return Transaction object representing the suspended transaction. exception SystemException Thrown if the transaction manager encounters an unexpected error condition.
