I am sorry but I do not use Red Hat Developer. I suspect that Developer is using JMX to deploy the applications, rather than copying the files to the deploy directory, and therefore the war file is not located in the deploy directory. If the app server is not running, and you copy the war file to the deploy directory, and then start the app server, the app server will deploy the application. (If this is your situation and you believe the app is not being deployed, post the console log from when you started the app server, and post a 'dir' of the deploy directory.) If the app server is already running and you copy the war file to the deploy directory and the app does not deploy, then most likely Developer modified the app server to turn off hot deployment. You can check this by looking at the last MBean on server/default/conf/jboss-service.xml, specifically the attributes ScanPeriod and ScanEnabled.
