RE: Problems with callbacks

Thanks for the fast response.

Do you know if there is a possibility to implement an server "without inheritance"? 
Because the server (he is already given, and I can`t change anything on it) waits for an reference to an special object ( TCClient), so I musst inherit form it. (to be abel to cast.) 
But that means, that I can`t inherit from other objects like ClientPOA or something else (Because I`m using Java and there it is impossible to inherit from more than one class).

Seems all to be very difficult..

>What I mean is: I can connect to an server, and now I want that he can talk to the client using callbacks. Therefor there is already an method to register the client. These method gets an reference to an objecte of the client type (respectively of the interface type from Client). But I can't simple give the client reference with "this". By doing so, I get an "org.omg.CORBA.BAD_OPERATION: The delegate has not been set" Exception.
