There is another rather well-established solution to the problem of redeploying any Java applications (either web profile only or full blown enterprise edition) and it is JRebel from ZeroTurnaround - have a look, quite interesting: http://www.zeroturnaround.com/jrebel/features/

They're different problems. This is about running two versions of a web application concurrently and migrating clients from old to new gracefully, without bringing down the site. JRebel is about hot-swapping the bytecode that's loaded into the JVM.
