[omniORB] Dynamic Servant Creation

You can do this with 'normal' CORBA. You can construct servants (and their corresponding CORBA objects) on the fly, when you need them.

But I don't think that's what you're asking...

You need to look up "Servant Activator". If you create a POA with USE_SERVANT_MANAGER policy, and then install a ServantActivator as its servant manager, then you can create servant objects when the client tries to connect to them.

Obviously you need to obtain the object reference from somewhere: You can use PortableServer::POA::create_reference_with_id() to create object references without the need to have an actual servant.
