key, with a collection of remote references returned to the client.
B. When a client calls a multiple row finder method, the home object

method. The home object instantiates a collection of remote objects for
each primary key, with individual remote references returned to the
client.
C. When a client calls a multiple row finder method, the remote object
invokes the corresponding ejbFind...() method. The remote object then
