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.
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.
