JBoss AS 7 est sorti pendant l’été 2011. Cette version est une véritable révolution pour tous les utilisateurs JBoss : temps de démarrage et de déploiement record, techniques d’administration renouvelées, configuration simplifiée et plus expressive,… Dans cette présentation, j’explique ces nouveautés et je les montre avec des vrais morceaux de ligne de commande et peu de cloud.
