Have you tried deploying using Eclipse Juno + JBoss Tools, or JBoss Developer Studio?
I don't think the JBoss maven plugin is intended to work for a "hot deploy" scenario.
Thanks for quick reply Stephen... I guess I have installed JBossAS Tools in my Eclipse Juno not the JBoss Tools. Does installation of JBoss tools required in order to resolve my issue. If So, why JBoss made this simple configuration as such a big deal? I have FileSync installed for hot deployment. It's working for any other changes except .xhtml,.js,.css when I refresh the browser.
