That's the correct way to do it.

The IDL to C++ mapping is very difficult and can't really be explained
over a mailing list. You can download a copy of the mapping from the
OMG website. You should also get the book: Advanced CORBA Programming
with C++ by Henning & Vinoski. That book is really not optional if you
are going to try to learn CORBA in C++.
