- Method Detail
  - begin
```
void begin()
    throws NotSupportedException,
           SystemException
```
    Create a new transaction and associate it with the current thread.
    
    Throws:
    
    NotSupportedException - Thrown if the thread is already associated with a transaction and the Transaction Manager implementation does not support nested transactions.
    
    SystemException - Thrown if the transaction manager encounters an unexpected error condition.
  - commit
```
void commit()
     throws RollbackException,
            HeuristicMixedException,
            HeuristicRollbackException,
            SecurityException,
            IllegalStateException,
            SystemException
```
    Complete the transaction associated with the current thread. When this method completes, the thread is no longer associated with a transaction.
    
    Throws:
    
    RollbackException - Thrown to indicate that the transaction has been rolled back rather than committed.
    
    HeuristicMixedException - Thrown to indicate that a heuristic decision was made and that some relevant updates have been committed while others have been rolled back.
    
    HeuristicRollbackException - Thrown to indicate that a heuristic decision was made and that all relevant updates have been rolled back.
    
    SecurityException - Thrown to indicate that the thread is not allowed to commit the transaction.
    
    IllegalStateException - Thrown if the current thread is not associated with a transaction.
    
    SystemException - Thrown if the transaction manager encounters an unexpected error condition.
  - rollback
```
void rollback()
       throws IllegalStateException,
              SecurityException,
              SystemException
```
    Roll back the transaction associated with the current thread. When this method completes, the thread is no longer associated with a transaction.
    
    Throws:
    
    SecurityException - Thrown to indicate that the thread is not allowed to roll back the transaction.
    
    IllegalStateException - Thrown if the current thread is not associated with a transaction.
    
    SystemException - Thrown if the transaction manager encounters an unexpected error condition.
  - setRollbackOnly
```
void setRollbackOnly()
              throws IllegalStateException,
                     SystemException
```
    Modify the transaction associated with the current thread such that the only possible outcome of the transaction is to roll back the transaction.
    
    Throws:
    
    IllegalStateException - Thrown if the current thread is not associated with a transaction.
    
    SystemException - Thrown if the transaction manager encounters an unexpected error condition.
  - getStatus
```
int getStatus()
       throws SystemException
```
    Obtain the status of the transaction associated with the current thread.
    
    Returns:
    
    The transaction status. If no transaction is associated with the current thread, this method returns the Status.NoTransaction value.
    
    Throws:
    
    SystemException - Thrown if the transaction manager encounters an unexpected error condition.
  - setTransactionTimeout
```
void setTransactionTimeout(int seconds)
                    throws SystemException
```
    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.
    
    Parameters:
    
    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.
    
    Throws:
    
    SystemException - Thrown if the transaction manager encounters an unexpected error condition.
