Hi, I use omniOrb and Python to connect to Visibroker Orb. In the Visibroker code, after the IOR has been send, a _non_existent call is done to check if the orb is there but htis check always fails. Can anybody help me out? I am running omniorb 4.0 and Visibroker 4.5 Cheers, Joost -- Joost van Lawick E: joost@lawick.nl W: http://www.lawick.nl/
