Those steps are correct if you want to start with a clean deployment. Hot deployment is easy - simply copy the EAR file to the deploy directory. The app server will undeploy the old app and deploy the new one. There are various situations under which this will fail, mostly having to do with how your application attempts to maintain state and the fact that the new app will have a different class loader than the old app. My rule-of-thumb. If hot deployment works, great. If not, do the steps you outlined (usually you do not need steps 3 and 4).
