What you need to do, is create a class-descriptor that describes "Object",
and all it's persistent derivative objects. Then OIDs are unique across
the whole system, and more imporantly when you load an Object.class with
OID 5, it will know it has to look at all the tables to find it.

Then how do I convert '5' into an object? Don't I still need to use a
org.apache.ojb.broker.Identity? How do I allocate an Identity if I don't
know the class?
