I’d like to be able to register and unregister (install and remove?) webapps dynamically, while the server is running. Tomcat, at least, has this manager application which allows this.
This would avoid the lengthy deployment phase, since the files don’t have to be copied to the Tomcat home dir.
Another advantage (the main one, IMHO) is that it restarting an application is much faster this way. Sometimes, the app does stuff on startup.
