Hi Paul,

Assuming the Object Reference was created by a POA with the RETAIN
ServantRetentionPolicy (for example, the RootPOA), or a POA with the
USE_DEFAULT_SERVANT RequestProcessingPolicy, you can call
reference_to_servant() on the POA the Object Reference.

If there's a Servant (implementation object) in the Active Object Map,
or a Default Servant, currently active to service requests on the
Object Reference, it will be returned.  Otherwise the call will throw
the ObjectNotActive Exception.

Be sure to call _remove_ref on the returned Servant to avoid leaking.

Regards,
Conor
