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

[techy_bolek]

I've no idea what are you trying to do. Firstly, you say you want to connect
a C++ client to Java server but you throw a C++ server code. Secondly, my
assumption was that the you were using CORBA but I see a J2EE 3.0 session
bean in your Java code.
