I would like to ask.
If I set my scheduler daily at 3 PM. It will run at that time. But if the scheduler already running at that time and I change my server / local time to 2 days from now, the scheduler automatically run. Is there any way to prevent it? I’ve been searching all over Google and haven’t found the solution yet. Thanks in advance.

HI,
I have written 12 schedulers using the above concept. My question is how many schedulers can the server handle. Is there a limit for the number of schedulers we write?

Hello mkyong,

Thanks for the tutorials. Does Spring 2.5.6 supports quartz versions > 1.6 ?

When I try to do so for 2.2.0 / 2.0.2 / 1.8.6 – I get following error :
org.quartz.SchedulerException: ThreadPool class ‘org.quartz.simpl.SimpleThreadPool’ could not be instantiated.
[See nested exception: java.lang.ClassCastException: org.quartz.simpl.SimpleThreadPool cannot be cast to org.quartz.spi.ThreadPool]

There is no direct reference given to ThreadPool in code/beans.

Also I observed that, on upgrading the quartz version – the groupid also changes to ‘org.quartz-scheduler’ from ‘opensymphony.quartz’.

Thanks,
Dhananjay

Is there any way to pass encrypted Database password using DirectSchedulerFactory class or any other way to acheive the same.

Hi Sir,
I am encountering a problem with Quartz scheduler.
I am using quartz 2.1.5 version with Spring 3.0.
The scheduler job runs fine, but when I undeploy the application on Jboss server, the quartz scheduler shutdowns but some thread will not be released and server hangs.It will not allow to teminate the process. I tried many options like destroy method, interrupt jobs on shutdow, make quartz daemon thread, shutdown hok plugin etc in which even single thing didn’t work. please help me overcoming this.
