I notice that deployed WARs are wrapped in MBeans. Is it possible to add code/config files to the WAR in order to expose more methods or attributes to be presented by the management console when accessing that web-app's wrapper MBean?

Case in point: We have an app that reads config information from a database table at startup. It would be nice to be able to change the config table and ask the app to re-read the config parameters without having to stop and start the webapp by presenting a JMX operation.
