Reschedule quartz trigger

I am trying to learn quartz. I have main method



Which works fine. It prints to the console on 3rd day of the week at 12:38 pm.
Now, what I want to do is to reschedule the trigger, so that it deletes the previous stored trigger and creates a new trigger with new schedule.

I read a lot of things at a lot of places but I just can't seem to understand clearly what I actually have to do, for ex:



and also this:

// Define a new Trigger

// tell the scheduler to remove the old trigger with the given key, and
// put the new one in its place


but I can't understand the approach(I do understand what is happening in the code though). Thanks in advance.

Hi arushi,

Though I'm not much aware of quartz (looks like a job scheduler) - I think this question is more quartz specific than Java specific.

Did you try to get in touch with somebody who knows quartz?

Yes it is, but I could not find Quartz forum here. And I don't know people who know quartz so I'm stuck all by myself.

Yes that is why I couldn't move your post to proper forum

Anyways I just checked API documentation (please note that I have zero knowledge in quartz internals) and found that rescheduleJob(<-click) needs a new trigger with same job name and group name.

I can see that your new trigger does not contain job name. Maybe you can try forJob(<-click).

I hope this helps.

I put this in "Other Application Frameworks". It may not be the best forum for it, but it fits. Quartz is a framework for doing scheduled operations, much like the Unix "cron" service does.

I haven't worked with Quartz lately, but I believe it supports both one-shot tasks and regularly repeated tasks. You can keep the task schedule in persistent storage or just in-memory.

There's also a Spring Scheduling module and it supports Quartz.

I think the question was in how to get work done at a regularly-scheduled interval, and yes, Quartz is very much about that. You don't have to manually re-schedule repeated tasks, just set up the time/day(s) that it should do the task and Quartz will handle dispatching that task automatically.
