JBoss, Selenium, Maven, Hudson, M2 Extra Steps & Files Found Trigger plugins - how do all these work together in a continuous build + Integration test life-cycle ?

The Story - The Use Case:

We have two projects with two war artifacts which need to be deployed to a JBoss Application Server, whilst both webapps share a common base configuration, although the release life-cycle of each war have no correlation to the other.

In production both application servers are running & serving one another thus, Integration test should cover both JBoss instances & test their web services.
