For all intents and purposes, the two apps are independent (unless you code the apps to interact). They can each use their own login domains, their own databases, etc. You can start and stop the apps independently. For each app JBossAS creates MBeans that can be used to stop, start and even undeploy the app. Of course all of this happens while JBossAS is running - you never stop it.
