This solution is not acceptable for my application: I need to use a specific TCP port (and only one)...<br>
It should be possible to "force the object key", on the servant side, (before or after instantiation) no ? It would be "cross-orb" capable, and smarter...<br>
<br>
Thanks<br>

Or there's another way, avoiding the use of those and being cross-orb capable :<br>
You juste need to stringify the top servant's IOR, create a socket on the server within a separate thread before entering the ORB's run method (which is blocking). That thread should wait for connections, send the stringified IOR, close the socket and get back on waiting.<br>
That work for me fine for several years now, with both java and C++ clients.<br>
<br>
This avoids you from implementing a name service. The only things the clients should now is the name ou address and port number of the server.<br>

Hello,<br>
Quite all is in the mail subject... I need to develop a network application client/server "easy to deploy".<br>
Is it easily possible to develop such an application with the omniORB API, which can connect a servant directly, just using an IP adress and a TCP port (and maybe some others static informations...) ?<br>

Check the docs (and mailing list archives) for "corbaname" and "corbaloc".<br>
