Connexion à un Naming Service (TAO)

**Ydalb** · 27/08/2009, 10h33

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 :

Code :

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 :

Sélectionner tout - Visualiser dans une fenêtre à part

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.
