      org.jboss.system.ServiceMBeanSupport
          org.jboss.ha.jmx.HAServiceMBeanSupport

                      org.jboss.varia.scheduler.DBScheduleProvider

All Implemented Interfaces:: AbstractScheduleProviderMBean, DBScheduleProviderMBean, org.jboss.ha.jmx.HAServiceMBean, org.jboss.ha.singleton.HASingleton, org.jboss.ha.singleton.HASingletonMBean, javax.management.MBeanRegistration, javax.management.NotificationBroadcaster, javax.management.NotificationEmitter, org.jboss.system.Service, org.jboss.system.ServiceMBean

public class DBScheduleProvider
extends AbstractScheduleProvider
implements DBScheduleProviderMBean

This Provider get its Scheduler from a Database and then adds all the Schedules to the Schedule Manager. The "SQL Statement" must deliver the following attributes: Index Content Data Type ---------------------------------- 1., Target, String 2., Method_Name, String 3., Method_Signature, String 4., Start_Date, String 5., Period, long 6., Repetitions, int 7., Date_Format, String ATTENTION: The "Target" is Object Name of the target MBean as String, the "Method_Signature" is a list of attributes separated by colons which can contain:

NOTIFICATION which will be replaced by the timers notification instance (javax.management.Notification)
DATE which will be replaced by the date of the notification call (java.util.Date)
REPETITIONS which will be replaced by the number of remaining repetitions (long)
SCHEDULER_NAME which will be replaced by the Object Name of the Scheduler (javax.management.ObjectName)
any full qualified Class name which the Scheduler will be set a "null" value for it

The "Period" is an long value greater than 0. The "Repetitions" can be set to "-1" which means unlimited repetitions. The "Date_Format" can be null or blank to signify locale usage
