RE: What are the call back methods in Session bean

Session callback methods
setSessionContext();
unsetSessionContext();
ejbLoad();
ejbActivate();
ejbPassivate();
ejbRemove();

Entity bean call back methods
public void setEntityContext(javax.ejb.EntityContext c);

public void unsetEntityContext();public void

ejbLoad();

public void ejbStore();public void

ejbActivate();

public void ejbPassivate();

public void ejbRemove();

In call back methods there is no ejbCreate() method
