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 Mkyong,

I have followed the procedure for setting up a Job Scheduler.But for Security purpose, I need to encrypt the DB password in quartz.properties.Currently I am using implementation class StdSchedulerFactory that reads configuration from properties file. Is there any way to pass encrypted Database password using DirectSchedulerFactory class or any other way to acheive the same.
Please help.Thanks.

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

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.
