Connexion à un Naming Service (TAO)
Bonjour,
Je développe une IHM qui doit parcourir un Naming Service pour y récupérer et lister tous les objets qui y sont référencés. J'avais dans un premier temps utiliser l' orbd pour mes test (Object Request Broker Daemon). J'arrivais à m'y connecter en local avec le code qui suit :

J'ai mis en gras la ligne ou ça bug (dans le code et le quote).
Pour info, je lance le Naming Service avec la commande :
Code:

xterm -e "/applis/ace-tao_5.5.1-1.5.1/TAO/orbsvcs/Naming_Service/Naming_Service -m 1"& |
Et la valeur du port $NameServicePort est bien à 1050.
Auriez-vous une idée pour résoudre ce problème ?
Cordialement.
