Question

I am looking into a web app that already uses Quartz.
In the web.xml there is:

<servlet>
  <servlet-name>QuartzInitializer</servlet-name>
  <display-name>Quartz-Init Servlet</display-name>
  <servlet-class>
    org.quartz.ee.servlet.QuartzInitializerServlet
  </servlet-class>
  <load-on-startup>5</load-on-startup>
</servlet>

What is the job of this servlet and it’s lifecycle?
I understand that it does some intialization for the quartz job scheduling but not exactly sure what.
Since there is no servlet-mapping for it, I assume that it is not supposed to handle requests.
Any help is appreciated.
Thanks

QuartzInitializerServlet starts the Scheduler (typically a StdScheduler) and its worker threads. The configuration will be loaded from the file quartz.properties.

If you are only using one scheduler, you can use QuartzInitializerListener
