Webservice : From Servlet
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 :

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
Citation:
org.apache.axis.client.ServiceFactory
alors que dans ma servlet j'ai effectué un import de :
Citation:
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.
