4062 Could not open Notes session --HELP--

I try to connect to my domino server over diiop/corba with a litle example. But it doesn’t work. On the server console there is a message:DIIOP server connected and DIIOP server disconnected. All in the same second. I read all descriptions, but i can’t find a solution.

Here is the stacktrace from my program:

org.omg.CORBA.MARSHAL: minor code: 0 completed: No
