Does anybody have experience with the integration of Java CORBA with other CORBA implementations?

We use Visibroker and have successfully deployed Java/CORBA and C++/CORBA in a production environment. We even have a bridge to allow VisualBasic to use native COM components to interface with both our Java and C++ services.

Additionally, we have clients using Websphere's ORB to access our services. Other customers use DNS Smalltalk Brokers and IBM Component Brokers talk to our servers.
