I'm just doing a mock test: There is a question: say, there is a one to many relationship, saleman --> customer saleman1--> collectionCustomers1 saleman2--> collectionCustomers2
if I call saleman1.setCustomers(saleman2.getCustomers()) What will happened? In the mock test, it says: saleman1 will get all customers have two collections (collectionCustomers1 and collectionCustomers2). saleMan2 will have no customers.
But in another book, It says for above situation, saleman1 only got collection of collectionCustomers2 and will lost collectionCustomers1.
Can you tell me which one is right answer! thank you.
Originally posted by mark ken: one more question: Is Bean's local home and local component interfaces must in ejb-jar file??? I think if there is remote home and remote component interfaces in ejb-jar is enough!
if only Local view is uzed for EJB, then both local home and local [component] interface must be included in ejb-jar file (plus bean class ofcourse).
if only Remote view is uzed for EJB, then both remote home and remote [component] interface must be included in ejb-jar file (plus bean class ofcourse).
if both Remote and Local views are used for bean, then Remote Home, Remote component, Local Home, Local component must present in ejb-jar.
