A?session bean can implement the
SessionSynchronization interface if it wants to be notified about the state of any transaction in which it is involved. Only stateful session beans using container-managed transactions can implement
SessionSynchronization. Its use is optional. The methods of
SessionSynchronization are callbacks made by the container into the bean, and they mark points within the transaction. Here is the
SessionSynchronization interface:
public interface javax.ejb.SessionSynchronization
{
public abstract void afterBegin() throws RemoteException;
public abstract void beforeCompletion() throws RemoteException;
public abstract void afterCompletion(boolean completionStatus) throws
RemoteException;
}
