jgroups demo projet de journalisation ne fonctionne pas

Question

Je veux savoir comment fonctionne jgroups en interne.Ainsi, j'ai fait deux cluster en suivant http://jgroups.org/tutorial/index.htmt site Web .cluster formé avec succès, mais je ne peux pas enregistrer le protocole FD garder le message vivant, le partage un message vers un autre noeud etc

I utilisé commande java suivante pour la formation d'amas

java -cp ":. log4j.jar: jgroups.jar:.:" -Djgroups.bind_addr = 127.0.0.1 -Djava.net .preferIPv4Stack = true -Djgroups.use.jdk_logger = true org.jgroups.demos.Draw -props tcp1.xml

java -cp ".: log4j.jar: jgro ups.jar:.: » -Djgroups.bind_addr = 127.0.0.1 -Djava.net.preferIPv4Stack = true -Djgroups.use.jdk_logger = true org.jgroups.demos.Draw -props tcp2.xml

<!-- 
    TCP based stack, with flow control and message bundling. This is usually used when IP 
    multicasting cannot be used in a network, e.g. because it is disabled (routers discard multicast). 
    Note that TCP.bind_addr and TCPPING.initial_hosts should be set, possibly via system properties, e.g.

merci me aider !!!

-Djgroups.use.jdk_logger=true signifie que vous n'utiliserez pas log4j2.

Utilisez la propriété système -Dlog4j.configurationFile=$HOME/log4j2.xml et le fichier log4j2.xml ci-dessous. Vous devez remplacer $HOME par votre homedir et noter que les fichiers JAR log4j2 doivent être sur le chemin de classe.
