public class ConfigurationService

extends ServiceMBeanSupport

implements ConfigurationServiceMBean

The ConfigurationService MBean is loaded when JBoss starts up by the JMX MLet.

The ConfigurationService in turn loads the jboss.jcml configuration when loadConfiguration() is invoked. This instantiates JBoss specific mbean services that wish to be controlled by the JBoss ServiceControl/Service lifecycle service.
