/**
 * Designate a stateful session bean method to receive the after begin
 * session synchronization callback.
 * 
 *
 * The after begin callback notifies a stateful session bean
 * instance that a new transaction has started and that the subsequent
 * business methods on the instance will be invoked in the context of
 * the transaction.
 * 

 *  This method executes in the proper transaction context.
 *
 * A bean must have at most one AfterBegin 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.
 *

 * @see BeforeCompletion
 * @see AfterCompletion
