Based on the conclusion at http://www.uk.research.att.com/omniORB/archives/2000-07/0037.html there is a bug on Java 1.3 side of things. As it is harder for me to implement a work-around at Java side, I wonder if it would be feasible to put that "NameServiceA" as the object key in omniORB sources, or does something rely on it being "NameService" ? -Harri
