Hi Team,

I am using a servlet say "QuartzServlet" that implements ServletContextListener. This servlet initializes the Scheduler using

Code:

SchedulerFactory sf = new StdSchedulerFactory("quartz.properties");
 Scheduler sched = sf.getScheduler();
 sched.start();

I want to use this scheduler instance in another servlet so that i can display the existing jobs and triggers in a jsp. Do i have to create a new instance once again like this

Code:

SchedulerFactory sf = new StdSchedulerFactory("quartz.properties");
 Scheduler scheduler = sf.getScheduler();

or get the running instance of the scheduler. If so, how can i get the instance. Please suggest me a solution for the above.

Why not in session or in ServletContext? Also as an static field of the servlet?

You could use RMI every time but I do not think is worthy. My (almost) Quartz newbie opinion.

So, if i use it in session, then can i use that the scheduler instance any where in the application, i.e, in multiple servlets( one to add job&trigger, one to display jobs, one to start the instance). If so, can you please guide me how to use it in session.

It is not a Quartz question but a servlets question:

Depends on your requirements and technologies that you are using. The drawback is, if attribute is non serializable it will be lost if you have clustering.

An alternative is sharing in ServletContext. (get/set) at application scope.
