Quartz Scheduler Tutorial

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
  Uses QuartzInitializerListener to 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
