Quartz, is a open source job scheduling framework, that let you scheduler a task to run on a predefine date and time. Happy learning Quartz 🙂
1. Quick Start
Hello world to Quartz scheduler frameworks.
- Quartz 1.6 hello world example
The old and popular Quartz 1.6.3, legacy system may still using this. - Quartz 2 hello world example
Latest Quartz 2.1.5 example, many APIs changed. - Quartz 2 JobListener example
Create a listener class and keep track the running jobs status. - Multiple Jobs In Quartz
Declares and run multiple jobs in Quartz. - List All Jobs In Quartz
List all the existing jobs in Quartz. - Trigger A Quartz Job Manually
JSF2 example, display all jobs and fire a specified job manually.
2. Integration
Some common Quartz integration with other frameworks.
- Spring 3 + Quartz 1.8 scheduler example
Spring 3 doesn’t support Quartz 2, but you still can use Quartz 1.x - JSF 2 + Quartz 2 scheduler example
UsesQuartzInitializerListenerto integrate with JSF, in fact, you can use this class to integrate almost any of the Java web frameworks. - Struts 2 + Quartz 2 scheduler example
Integrate Quartz 2 with Struts 2 directly. - Struts 2 + Spring 3 + Quartz 1.8 scheduler example
Integrate Quartz 1.8 with Struts 2 via latest Spring 3. - Struts 2 + Spring 2.5.6 + Quartz 1.6 scheduler example
Integrate Quartz 2 with Struts 1.6 via Spring 2.5.6. - Struts 1 + Quartz 2 scheduler example
Integrate Quartz 2 with Struts 1.x directly. - Struts 1 + Spring 2.5.6 + Quartz 1.6 scheduler example
Integrate Quartz 1.6 with Struts 1.x via Spring 2..5.6, a common combination in many old systems.
3. Common Errors
- IncompatibleClassChangeError : JobDetailBean has interface org.quartz.JobDetail as super class
- java.lang.ClassNotFoundException: org.springframework.transaction.TransactionException
- Quartz : org.quartz.SchedulerConfigException: Thread count must be > 0
I want a quartz job to not run at server startup,PLease let me know if there is any way to configure it
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?
I have my existing applicationcontext.xml and i created seperate xml for quartz scheduler and import this xml in to applicationcontext.xml. It is running in stand alone application but in web application the tomcat sever started but the app home page is loading continuously but not opening. Can you please help me in this.
When applying quartz 1.8 to spring web application it is loading continuously but the home page is not opening.
Can you post Spring 3 MVC with Quartz 1.8 example

Can you please provide me gradle dependency for Quartz Scheduler?
Could anyone please provide example for Spring + Quartz + Mysql example ? I need guidance or sample code would be much appreciated.
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.
good job
Can we use past date in Quartz?
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.

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 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.
