Erreur lors de l'appel d'un WebService.

Bonjour à tous,

Je fais actuellement un teste afin d'utiliser des WebServices écrit en java (jax-ws) depuis un client Silverlight4.
Je fais appelle à une méthode qui me renvoie une exception

Via le tester généré par glassfish, j'obtient la réponse suivante :

Si quelqu'un à une idée pour la solution, ce serait super sympa.

MasterSleepy.

Et avec autre chose que Silverlight ça donne quoi ?

Tu arrives à référencer et récupérer des données ? (avec un projet Console par exemple).

Je fais maintenant des testes depuis une appli console, Merci pour le conseil Skyounet ;) .
J'ai maintenant l'erreure suivante:

There was an error in serializing body of message : 'Unable to generate a temporary class (result=1).
error CS0030: Cannot convert type 'string[]' to 'string'
error CS0030: Cannot convert type 'string[]' to 'string'

Suivant le fix donné à cette adresse : http://support.microsoft.com/kb/326790/en-us
J'ai modifié les [][] par [] dans le fichier reference.cs.
Maintenant ca fonctionne sans planté mais je n'ai pas les bonnes données.
Ma propriété Rows n'étant plus [][] mais [] je ne récupère que le dernier élément.

Si qq1 à une idée, elle est la bien venue, car moi je commence à en manquer.

Merci.

Salut à tous,

Voilà pour clore ce sujet la solution.
J'ai demandé à la personne en charge des WS java de modifier l'output afin d'avoir un flux du genre :

Et maintenant le problème est résolu, le service est créé correctement dans VS2010 et je récupère bien tout mes données.
Pour moi le problème vennait de la définition de columnnames.
