If you have a library of classes that can be used to create a set of services, JMX beans, other managed beans, EJBs, etc, this library can be put into the servers classpath and then by deploying just deployment descriptors you can create new services, managed beans, EJBs, etc.
This feature was added previously to avoid creating JARs that contain only service XML files. Plus, with hot deploy tracking the file modifications it's like WYSIWYG editor (after the save of course).
