[omniORB] how to use _dispose() in factory?

You might try saving the BOA during initialization, and then call
dispose() using the BOA.

static CORBA::BOA_ptr p_BOA = CORBA::BOA::_nil();

extern  CORBA::BOA_ptr  get_boa () { return p_BOA; }

void main()
{
   ...
   p_BOA = p_Orb->BOA_init(argc, argv, (char*)Z(BOA_NAME));
   ...
   p_BOA->impl_is_ready(...);
}

Then, 

void BaseObjectFactoryImp::destroyObject( modest::BaseObject_ptr  me )
{
    get_boa()->dispose(me);  //decrements ref count from
object_is_ready()
}

This is effectively what we do with our Object Factory implementation.
(It should also make your server a little more portable, since the
_dispose() method is not standard CORBA, but BOA->dispose() is).
