That's my understanding too (although I haven't used the naming service
in ORBit/ORBitcpp since ORBit-0.5 days).

Generally the dance goes something like this (from the depths of my
memory).

compile CosNaming.idl to stubs (this is often done for you by ORBs -
does ORBitcpp do this and dump the stubs somewhere as part of make
install?).

Use the stubs in your code.
Use resolve_initial_references() to get the name service initial object
reference and go from there using the CosNaming C++ stubs.

_Advanced CORBA Programming with C++_ goes into detail about what to do
with the object reference you get back from
resolve_initial_references() in the Naming Service chapter. The sample
code should be OK without modification, but you might need to add you
own CosNaming stubs path to the includes list passed to the compiler.
