Bonjour

J'utilise le Guide JXSE_ProgGuide v2.5, et je suis en train d'essayer de faire tourner quelques uns des exemples utilisant le NetworkManager.

J'ai utilisé le "HelloWorld" mais j'ai une erreur due à une ClassNotFound.

J'ai ajouté les librairies JXTA et JXSE et essayé d'autres exemples du Guide utilisant le NetworkManager, mais j'ai toujours la même erreur.

Voici les libs que j'ai utilisées :
Jxse : http://download.java.net/jxta/ (jxse-lib-2.5.zip)
Jxta : http://download.java.net/jxta/jxta-jxse/2.4.1/ (jxta-lib-2.4.1.zip)

Vous trouverez ci-dessous le code du programme ainsi que le log file.

Merci de votre aide
Manuvd

PROGRAM
=========
package JXSE;

import net.jxta.platform.NetworkManager;
import java.text.MessageFormat;

public class HelloWorld {

public static void main(String args[]) {
NetworkManager manager = null;
try {
manager = new NetworkManager(NetworkManager.ConfigMode.EDGE,
"HelloWorld");
System.out.println("Starting JXTA");
manager.startNetwork();
System.out.println("JXTA Started");
} catch (Exception e) {
e.printStackTrace();
System.exit(-1);
}
System.out.println("Waiting for a rendezvous connection");
boolean connected = manager.waitForRendezvousConnection(12000);
System.out.println(MessageFormat.format("Connected :{0}", connected));
System.out.println("Stopping JXTA");
manager.stopNetwork();
}
}

Bonjour manuvd!

alors, vous avez trouvé la solution à votre problème ? moi aussi j'ai exactement le même message d'ATTENTION avec le même numéro uuid.
Comment faire pour s'en débarrasser ?

Si quelqu'un sait comment faire, ça serait gentil de me l'indiquer .

Bon courage à tous !

bonjour
j'ai eu le même problème chez moi et en faisant des recherches sur d'autres forums j'ai lu qu'il y avait des personnes qui ont réglé ce problème en incluant le "jxtashell.jar" qui se trouve dans les bib du shell. vous pouvez télécharger le shell et ses bib sur java.net.
personnellement ça na pas marché chez moi mais peut être que ça sera la cas chez vous.
tenez moi au courant
