How to use 3.0 interceptors in vb4.0.

[selcan]

I am trying to convert interceptor code written for vb3.0 to work in vb4.0. We have to use migration_c.hh header file which contains wrappers for the old interceptors.

Is anyone out there trying to work with vb4.0??
In previous versions we would implement the interface ClientInterceptorFactory. in 4.0 it seems taht we have to obtain a reference to the ClientInterceptorFactory instead. I am getting compilation errors such as:
Cannot create an object of an abstract class.
(class SampleServerInterceptorFactory contains or inherits at least one
pure virtual function e.g.
"interceptor_migration::ServerInterceptorDelegate
*interceptor_migration::ServerInterceptorFactory::create(const
IOP::TaggedProfile &)".)
SampleServerInterceptorFactory SampleServerInterceptorFactory::_instance;


If any one could help me out, i'd appreciate it.
Thanks,
