[Axis2] Paramètre d'une méthode toujours null

**Neikeur** · 02/01/2010, 23h58

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 :

Sélectionner tout - Visualiser dans une fenêtre à part

    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

Bonjour ,

Teste avec Axis2 c'est mieux , je ne suis pas sure mais je pense avoir lu qu' Axis 1.x pose toujours des problèmes avec les vecteurs et les list

A+

Bonjour,

J'ai un problème similaire (enfin je crois).

Je travaille sous Eclipse avec Axis2. En ce qui me concerne l'erreur est provoqué par le fait d'utiliser un wsdl que j'ai modifié (je change des minOccurs).

As-tu trouvé une solution?
