[Axis2] Paramètre d'une méthode toujours null
Bonsoir à tous,
je sèche depuis un petit moment sur un problème récurent au niveau de la consommation de mon WS. La méthode que j'ai suivie pour l'implémenter :
- Définition d'une classe JAVA de service
Code:
1

3
|
public Long getPages();
public Item[] getItems(Long page); |
- Génération du WEB Service associé avec axis, le tout sous netbeans

J'ai écris un petit client qui appel les méthodes. Aucun problème tant que je n'utilise pas de paramètre : getItems(Long page) déclenche un exception parce que le paramètre est toujours null !
Que ce soit mon client ou l'outil de test du webservice de netbeans, Axis génère toujours cette erreur
