Hi,
The whole concept of Domain mode is to have a centeralized controll over your whole domain.... Like deployment/Undeployment... etc. Everything should be achevable through Domain Controller (Rather than contacting individual JBos Servers which are part of domain)
In Domain mode we have a concept of "server-groups" (which are based on some profiles like ha, full-ha, full, default...etc). We Target applications to "server-groups" (Not to individual servers in Domain mode). So definitely you will not see any such MBean on Individual Server which you can use to deploy an application on a JBoss instance which is running as part of Domain mode.
