  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.
