Foil 41 Entity Bean Lifecycle - II

From Object Web Computing Technologies CPS714 Computational Science Information Track -- June 16 99. by H. Timucin Ozdemir


1 The instance becomes active when the container associates an EJB Object with the bean instance.
2 A container invokes ejbCreate() and ejbPostCreate() methods to inform the bean that it should be ready to receive method invocations.
3 After this point container delivers business and state synchronization calls (ejbLoad() and ejbStore()).
4 ejbLoad() callback informs bean to load its state from the data store and ejbStore() informs the bean to store its state to the data store so that the possibly cached information in the bean's fields is transferred to the stable storage.
