I have been (unfortunately..  :-) ) doing CORBA for a few years now,
and I can sympathize as I have made mistakes like this. However, in my
experience, if you are going to be doing CORBA in C++, you really do
need 2 things: The Henning and Vinoski "Advanced CORBA Programming
with C++" book, and a copy of the latest C++ mapping from the OMG. The
mapping document isn't that hard to read, and in fact, I find it under
specified. I wish they would say more. I do refer to it often though.

(Getting a new, better, more modern C++ mapping probably isn't going
to happen sadly)
