[omniORB] How to connect and call C++/Qt client and Java Server

[Juaci Monteiro de Carvalho]

Ok, thanks for your help.
I'm beginner, I was thinking that code (Corba) would be to use for client.
It's possible you send me an example C++ Corba for client and using 
javaEE5 (server)?
This I'm trying to do.
