-Djboss.service.binding.set=ports-01

Changer le port d'écoute sur un serveur Apache (httpd)

Aller dans le répertoire d'installation de votre serveur Apache
Ouvrir le fichier (mon serveur est sur c:)
C:\Program Files (x86)\Apache Software Foundation\Apache2.2\conf\httpd.conf
Changer la ligne "Listen 80" pour correspondre au port entrant (ouvert ?) que vous voulez.

Exemple: changer le port en "83"

Extrait du fichier httpd.conf
# Listen: Allows you to bind Apache to specific IP addresses and/or
# ports, instead of the default. See also the <VirtualHost>
# directive.
#
# Change this to Listen on specific IP addresses as shown below to
# prevent Apache from glomming onto all bound IP addresses.
#
#Listen 12.34.56.78:83
Listen 0.0.0.0:83
Listen [::0]:83
