How to programmaticly schedule many tasks ?

[dmary]

Hi all,

I was reading many docs and post on scheduling into Jboss and I didn't really found any good solution. I use Jboss 4.05 GA in clustered environnement.

I need to create and schedule programmaticly each days , at any time, many tasks which require at least one parameter (this parameter can differ and change behavior of tasks)
I need as I said I use cluster, to execute tasks on only one node into the farm, but I want to register new tasks anywhere in the farm.


Do I need to register new tasks with only a JMX Schedule Manager ?
or any other way ?

As I will register for example 200 tasks by days at any time (these tasks will run once at a given time), do I need to declare only one Scheduler config (org.jboss.varia.scheduler.Scheduler) or one SchedulerProvider config (org.jboss.varia.scheduler.SingleScheduleProvider | org.jboss.varia.scheduler.DBScheduleProvider)?

I'm completly lost and I need help !!

For moment, I've succeed in create one task programmaticly, but :
- first I add a schedule which must start 30 sec after
- I stop the server which add schedule
- I didn't see the schedule started on one other node on my farm (3 servers)

Did I forgot something ?

MBeanServer server = MBeanServerLocator.locateJBoss();
 ScheduleManagerMBean schedule = null;
 try {
 ObjectName pProvider = new ObjectName("jboss:service=SingleScheduleProvider");
 ObjectName pTarget = new ObjectName("jboss:service=SchedulableMBeanExample");
 schedule = (ScheduleManagerMBean) MBeanProxyExt.create(ScheduleManagerMBean.class, "jboss:service=ScheduleManager", server);
 String[] params = {"NOTIFICATION", "DATE", "REPETITIONS", "SCHEDULER_NAME", "java.lang.String"};
 Date d = new Date(Calendar.getInstance().getTime().getTime()+30000);
 System.out.println("adding task for "+d);
 schedule.addSchedule(pProvider,pTarget,"hit",params,d,2000,9);
 } catch (Exception e) {
 e.printStackTrace();
 }

<mbean code="org.jboss.varia.scheduler.SingleScheduleProvider"
 name="jboss:service=SingleScheduleProvider">
 <depends >jboss:service=mypartition</depends>
