RMI Connection refused to host: 127.0.0.1
J'ai tenter de faire une application rmi de base pour tester. Elle fonctionne très bien en local, mais elle plante dès que je tente de l'utiliser à distanse.
J'ai trouvé des posts concernant ce problème mais rien ne semble foncionner. J'ai joint à mon post le résultat de l'exécution de mon appliquation avec le plus d'information possible et le code de mon application.
je vais laissé mon serveur ouvert pendant un certain temps si vous voulez essayer.
