Hot pluggable extensions for access management system
A file containing code for customizing a server's functionality can be “hot plugged” into the server without requiring server restart. The file is added in a class path of its own. The server's class path is not modified during this process, and, consequently, the server does not need to be shut down or restarted. Changes are made to the class-loading pattern of a JVM.
