## org.jboss.configuration
Class ConfigurationService

    java.lang.Object
      |
      +--javax.management.NotificationBroadcasterSupport
            |
            +--org.jboss.util.ServiceMBeanSupport
                  |
                  +--org.jboss.configuration.ConfigurationService

All Implemented Interfaces:
  ConfigurationServiceMBean, javax.management.MBeanRegistration, javax.management.NotificationBroadcaster, Service, ServiceMBean

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.

  Throws:
    `java.lang.Exception` - Failed to load.

### save

    public java.lang.String save()
                          throws java.lang.Exception

  Specified by:
    `save` in interface `ConfigurationServiceMBean`
  Throws:
    `java.lang.Exception` - Failed to construct configuration.

### saveConfiguration

    public void saveConfiguration()
                           throws java.lang.Exception
