I don't understand what the problem is. Servant locators don't deal
with object references at all -- they deal with servants.

In a function that must return an object reference, there are two
cases. The first is that the function returns generic CORBA::Object,
in which case you can return CORBA::Object::_nil(). The second is that
the function returns a specific object reference type, in which case
you can use the right _nil() function for that type.

Cheers,

Duncan.
