Get info of all server group in the JBoss EAP domain. This command should be run in the Domain Contoller with management port is running on 9999 (Not the port used by web UI admin console):

/Servers/EAP-6.4/bin/jboss-cli.sh -c --controller=localhost:9999 "ls /server-group"
main-server-group
other-server-group

Deploy WAR to one of the server group e.g. other-server-group:

/Servers/EAP-6.4/bin/jboss-cli.sh -c --controller=localhost:9999 "deploy ~/playground/HelloWebApp/target/HelloWebApp.war --server-groups=other-server-group"

If you already setup an HTTP server with mod_cluster as a load balancer then access:

http://localhost/HelloWebApp/
