Scheduler

[Prashanth_02a]

Is it possible to update SCHEDULER CRON EXPRESSION value dynamically, with a value coming from an AEM component dialog ? Please help....!

My scenario: I need to send email and sms reminders to webinar subscribers 1 hour before the webinar starts, there will be a webinar scheduled every week and scheduler should run at that time, scheduler cron expression should be updated automatically when a time is authored for a webinar in the component.

you can use Job manager to schedule and unschedule jobs

You can try to access and modify osgi config for scheduler while you are authoring your component. You can either provide cron expression through authoring or make a list of pre defined cron expression and select any out of the list on the basis of auhoring value.

As you will commit the value in osgi config, scheduler will be configured with @MODIFIED annotation.

Hi,

I don't think that it should be done this way. Instead I would have the scheduler hourly and check if email needs to be sent (by checking all webinars which are not already happened). Or you could use a scheduled job as mentioned by @arunpatidar , which is probably the best way to handle this.
