If you are curious what's happening in this case is that _narrow attempts to open IIOP connection to target object and as part of this code there is also a logic which tries to obtain ContextEstablishmentPolicy from the target object reference. By spec, if such policy is not associated with the target object Object::_get_policy should throw CORBA::INV_POLICY exception which is caught and code continues... See iop.cc, and seek for MICO::IIOPProxy::make_conn (CORBA::Object_ptr obj, CORBA::Boolean& timedout) if you are interested in seeing the code in question. > As for the demo/services/naming example, i've tested it and it seems to > work.

Hmm. One thing is that nsobj and nc variables are NOT NULL from the C++ point of view. They are both _var smart pointers allocated statically on the stack so they should not be NULL anyway. The question here is if nsobj.in() and/or nc.in() are NULL or not, that means if the pointers saved into the smart pointers are null or not. That's why CORBA::is_nil(var) is usable here and I certainly recommend its usage here... > I don't think there is smth wrong with argv[3] because with TAO it works > just fine. I still think this may be a culprit, if you don't believe try to use the same corbaloc in demo/services/naming example... Of course I may be mistaken here!
