[omniORB] Retrieving the ObjectId from an Object Reference

Hello,

In fact I need to do this in general, from a given IOR any CORBA Object
(mine are all
clients and servers at the same time) must retrieve the ObjectID associated
with it.
I'm not sure but perhaps the get_interface () can do this for me.

I always use the RootPOA to create nem POA instances for a given CORBA
Server,
this is done because I need to specify some policies and change the default
value of other policies
that already come with the RootPOA.

I asked this because of the restrictions imposed by the CORBAv2.6
specification,
it explicitly says that the POA used to invoke something like
reference_to_id() or servant_to_id()
must be the same as used to create the IOR.

Thanks once more for the tip,
