When an app is redeployed there usually are a couple of seconds (minutes - depending on the size of the app being redeployed) in which the application is not available.
Is there any mechanism that can be switched on such as JBoss keeps the old application online until the new version is fully-deployed/installed ?
Take a look at https://community.jboss.org/thread/236663 where it's just being discussed. WildFly and AS7 are very similar in this regard.
