Bonjour,

Je développe actuellement une application Web Dynpro Java sur Netweaver CE 7.2 et je rencontre une erreur lors de l'execution d'un web service. En gros, c'est une application Java basée sur un framework MVC propriétaire à SAP Netweaver. Etant donné qu'il n'y a pas de section correspondante à SAP Netweaver mais que c'est du développement Java, je me permets de poster mon problème ici.

J'ai publié un WS publique dans le service registry du serveur Netweaver (sorte de bibliothèque de Web Services). Lorsque je le teste via le WS Navigator (outil interne pour tester un web service publié) tout fonctionne bien. En revanche, côté Web Dynpro (application Java), ça ne fonctionne pas. Le web service que j'essaye d'importer fait partie d'un endpoint qui délivre 3 méthodes:

- logon (connection qui donne en réponde un session ID).
- logout (deconnection).
- ping (fonction qui ne prend rien en entrée et qui renvoie la version de Business Object Data Services afin d'indiquer que la connexion a bien été établie).

J'ai testé l'execution de la fonction logon dans SOAPUI et tout fonctionne correctement. En revanche, Lors de l'execution de l'application WDPJ, j''ai l'erreur suivante que je n'arrive pas à résoudre:

javax.xml.rpc.ServiceException: Configured BindingData b38c8d65-1eb9-40a3-aae7-ffd97f5ccf0d is not compatible with those available in the Webservice clinet framework. Configured BindingData has operation Ping operations, which is not found in the Webservice client framework configuration.

Et la trace d'execution correspondante:

5

Quelqu'un aurait une idée pour me venir en aide pour débugguer ce Web service ?

Merci par avance,

Thibault

Il s'agit en fait d'un bug sur le serveur applicatif, et non d'une erreur au niveau de l'implémentation du Web Service.
