You can do what you want, as long as your C++ compiler supports
dynamic_cast<>. If you don't have dynamic_cast<>, you're out of luck
I'm afraid.

You need something like the following. The syntax might be slightly
wrong, but you get the idea:

> class A_i {

>         B_i* impl = ???
>                !!! How can get from B_ptr corresponding B_i?
>                !!! Or, that too the most POA_B_tie, or _impl_B

  PortableServer::Servant svt = poa->reference_to_servant(the_b);

  POA_B_tie<B_i>* tie = dynamic_cast<POA_B_tie<B_i>*>(svt)

  if (tie) {
    B_i* bimpl = tie->_tied_object();
    // Do something with bimpl
  }
  else {
    // Servant isn't the right type
  }


Cheers,

Duncan.
