Jim,

IAS 4 provides the ability to use primary keys as parameters
to finder method.
Alternatively, you could have the finder method take the
Address remote references as a parameter:
public Collection findByAddress(Address a) ...;
which seems a little more object-oriented, to me, instead
of dealing always with primary keys.
See our example:
<ias>/examples/ejb/pigs
for details.
