1. return types must meet rmi/iiop. which in general means no primitives.
2. simple answer... yes.. except as the primary key.
3. according to the spec... on entity beans... ALL primary keys MUST be
objects, not primitives. If you want to use primitives you wrap them in a
compund key class. so as the fields of a primary key... yes, otherwise no.
