Designate a stateful session bean method to receive the before completion session synchronization callback.
The before completion callback notifies a stateful session bean instance that a transaction is about to be committed.
This method executes in the proper transaction context.
Note: The instance may still cause the container to rollback the transaction by invoking the setRollbackOnly() method on the session context or by throwing an exception. A bean must have at most one BeforeCompletion method. The signature of this method must observe the following rules:
- The method must not be declared as final or static.
- The method may have any access type.
- The return type must be void.
- The method must take no arguments.
A stateful session bean class may use either the SessionSynchronization interface or the session synchronization annotations, but not both.
Since:

EJB 3.1
