 public class TomcatStopListener implements ServletContextListener {


  public void contextDestroyed(ServletContextEvent arg0) {

   // How to get reference of already running Quartz Scheduler  here??


      }  

}

On the stop of tomcat server, I want to stop the quartz scheduler to avoid errors, I know scheduler.shutdown(); but how can i get the reference to the scheduler here?

Answer 1

If you have used QuartzInitializerServlet to initialise your Quartz, then you can do something like

 StdSchedulerFactory factory = (StdSchedulerFactory) ctx
            .getAttribute(QuartzFactoryServlet.QUARTZ_FACTORY_KEY);

inside your contextDestroyed method, where ctx is your ServletContext.
StdSchedulerFactory instance is stored into the ServletContext.
