This 'Hot deployment' allows for greater flexibility, since there is now a place to update the resource. If the application server supports hot deployment of EAR file, then update will take effect immediately if the application is redeployed (). However, for each WAR can locate the resource, you have to put the path to the resource file in the file MANIFEST WAR package. It would be even better to have scripts for automatic deployment.

Web servers provides 'hot deployment' functionality in which we are able to modify server side component. So this leads to automatic loading of new component. This feature is the hot deployment of components via the web interface. It improves developer productivity that can change the diagram, deploy and test a few seconds without having to restart the application server. This redeployment is very fast and can even keep the objects in an http session.
