Web service et J2ME par elmagique - page 1

Bonjour,

j'ai voulu utiliser le web service pour authentifier un client mobile (développé en J2ME),

pour ce la,

j'ai commencé par créer le web service, pour le moment, et pour simplifier les taches, j'ai crée
une simple méthode getResponse qui retourne dans tout les cas un String="True".
Le fichier WSDL généré est le suivant:

Les caractéristique de ce service sont:

Endpoint
Service Name: {http://MyPackage/}MyServiceService
Port Name: {http://MyPackage/}MyServicePort

Information
Address: http://localhost:8080/WebApplication2/MyService
WSDL: http://localhost:8080/WebApplication2/MyService?wsdl
Implementation class: MyPackage.MyService

La MIDlet à partir de laquelle je vais appeler le service est la suivante:

Quand je fait un Run, j'obtient un erreur signalant la ligne:

Citation : Ligne signalée

connexionServeur.call(null, envelope);

Il parait que c'est un problème d'url ,touchant

private String urlService = "http://localhost:8080";
private String nomService = "url:http://localhost:8080/WebApplication2/MyService?wsdl";

L'erreur que j'obtient aprés l'appui de la commande OK pour s'authentifier est:
