IllegalStateException:
Thrown if the current thread is not associated with a transaction.
SystemException:

Exceptions
SystemException:

rollbackback to summary
public 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.

Exceptions
IllegalStateException:
Thrown if the current thread is not associated with a transaction.
SecurityException:
Thrown to indicate that the thread is not allowed to roll back the transaction.
SystemException:
Thrown if the transaction manager encounters an unexpected error condition.
setRollbackOnlyback to summary
public 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.

Exceptions
IllegalStateException:
Thrown if the current thread is not associated with a transaction.
SystemException:
Thrown if the transaction manager encounters an unexpected error condition.
setTransactionTimeoutback to summary
public 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
