AXIS: Exception: "No Deserializer found to deserialize a "
Bonjour,
Je suis nouvelle en ce qui concerne Axis et depuis hier je deviens folle en essayant de trouver mon erreur!!!
Pourriez-vous me suggérer une solution?
Merci
Je ne sais pas les informations dont vous avez besoin... aussi je vous donne le programme server, le wsdd et le programme client. L'application est simple car je voulais seulement m'assurer que je pouvais obtenir une information avec AXIS... mais je ne peux pas!!
L'application est AIServicio.java qui contient une procédure de modification d'un paramètre. L'objet Output est retourne seulement un code d'erreur et l'erreur elle-même.
Le client est AIClient.java qui appelle cette procédure et écrit le resultat sur la page WEB-
==================================
J'utilise Axis 1-4 et Tomcat 5.1.9.
J'obtiens l'exception suivante:
No Deserializer found to deserialize a 'http://schemas.xmlsoap.org/soap/encoding/:string' using encoding style 'http://schemas.xmlsoap.org/soap/encoding/'.
