Try deploying your war as an exploded archive and see if that gets around the problem. Also, is JBossAS running when you deploy the war? If so, it could be trying to deploy the war before it is fully copied over. That sometimes causes problems like this. If that is the case, a workaround is to copy the war to a temporary location on the same diska partition as JBossAS, and then move the war file into the deploy directory.
