Using Scheduler with trigger

Question

Hi, I am trying to modify the following example to use trigger instead of "IntervalSchedule". It seems that the notification doesn't work. Any idea?
http://www.oracle.com/technology/tech/java/oc4j/1013/how_to/how-to-scheduler-jms/doc/readme.html
Here is my modification. I commented out a few lines and added trigger.
// adds a scheduler job
private JobHandle addJob(long startsIn,
long interval,
long endsIn) {
JobHandle jh = null;
try {
String desc = "OracleAS Scheduler Demo Job";
Scheduler s = getScheduler();
IntervalSchedule schedule = new IntervalSchedule();
Calendar etime = Calendar.getInstance();
Calendar ntime = Calendar.getInstance();;
etime.add(Calendar.SECOND,(int)startsIn);
ntime.setTimeInMillis(etime.getTimeInMillis());
ntime.add(Calendar.SECOND,(int)(endsIn-startsIn));
schedule.setExpiration(etime);
schedule.setInterval(interval*1000);
schedule.setEndDate(ntime);
// example usage to add a pure schedule based job
jh = s.add(desc,
"demo.Job",
schedule,
null);
Trigger trigger = new Trigger("CreateFile");
jh = s.add(desc,
"demo.Job",
trigger,
null);
s.notify(new Notification("CreateFile"));
} catch(Throwable t) {
System.out.println("Error adding scheduler job");
t.printStackTrace();
return jh;
}

Hi,
For 10g and up you should be using dbms_scheduler for scheduling. Some examples are here
http://download.oracle.com/docs/cd/B28359_01/server.111/b28310/scheduse.htm#i1033533
and the homepage is at
http://www.oracle.com/technology/products/database/scheduler/index.html
Here's an example that runs daily at 2am
begin
dbms_scheduler.create_job('myjob',
    job_type=>'plsql_block',
    job_action=>'dbms_lock.sleep(10);',
    start_date=>null,
    repeat_interval=>'freq=daily;byhour=2;byminute=0',
    enabled=>true , auto_drop=>true
end;
/Hope this helps,
Ravi.
