- public class DBScheduleProvider
- extends AbstractScheduleProvider
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

public void setDataSourceName(java.lang.String pDataSourceName)
- Sets the JNDI name of the Data Source. You have
to ensure that the DataSource is available when
this service is started.

- Add the Schedule to the Schedule Manager
- Specified by:
startProviding in class AbstractScheduleProvider
stopProviding
public void stopProviding()
- Stops the Provider from providing causing
the provider to remove the Schedule
- Specified by:
stopProviding in class AbstractScheduleProvider
getSignature
protected java.lang.String[] getSignature(java.lang.String pMethodSignature)
- Converts a string of method arguments (separated by colons) into
an array of string
getStartDate
protected java.util.Date getStartDate(java.lang.String pStartDate,
java.lang.String dateFormat)
- Converts the given Data string to a date
where not value means 1/1/1970, "NOW" means
now (plus a second), an long value means time
in milliseconds since 1/1/1970 and a String is
a Date string which is intepreted by a Simple
Data Formatter.
