Bonjour,

OS : Windows XP SP2
IDE : ECLIPSE Ganymede
Serveur : APACHE V6 + Axis2 1.5.1

J'ai implémenté une servlet dans une application web dynamique pour invoquer le serviceweb par défault de AXIS2 (Version).

Voici le code de ma servlet :

Code :

}

Mon répertoire est donc constitué :
ServletTest

J'exporte le projet sous la forme d'un fichier .war et le déploie sur Apache Tomcat. Jusqu'ici tout va bien !

Lorsque j'accède à l'adresse suivante :
http://localhost:8080/ServletTest/FirstServlet
j'obtient une erreur dans le fichier de log de tomcat

Je ne comprend pourquoi :
Dans Eclipse mon Web App Librairie contient bien le jar jaxrpc.jar
Et pourquoi l'erreur mentionne

org.apache.axis.client.ServiceFactory

alors que dans ma servlet j'ai effectué un import de :

import javax.xml.rpc.Call;
import javax.xml.rpc.ServiceFactory;

Merci à vous pour votre aide, je tourne en rond et je ne trouve pas la solution.
