Folks, A newbie question, so apologies if the answer is in a FAQ somewhere: I have 3 entity beans: Organisation, Contact, and Address. All use BMP. An Org can have many Contacts, and a Contact can have many Addresses. An Org can also have many Addresses. I intend to use Stateless Session Beans as facades to the Entity Beans. Question: How should the 1-to-many relationship be modelled? In the Entity Bean? e.g. a Vector of primary keys in the Organisation bean, populated by reading the Contact DB table directly? In the Session Bean facade? Some other mechanism?
