nested jobs in Quartz

Question

I have nested task to schedule:

(1). A daily master task downloading scheduling information, which is a List of job names with timestamps (2). schedule the job in the scheduling information I just downloaded according to its timestamp

I am not sure how the nested jobs work in Quartz. It seems that I need a CronTrigger triggering a job, which contains multiple SimpleTriggered jobs. Are there any way to do that? Are there any alternatives?

Thanks. Lily

Answer 1

They aren't really nested jobs.

You are correct in that the master job needs a CronTrigger. But when that job runs it will cycle through the list of jobs downloaded creating a job and a SimpleTrigger for each entry. You can get a Scheduler from the CronJob's JobExecutionContext and add the jobs to it.

And bingo, all your jobs are scheduled.

Answer 2

You basically need to run Quartz inside of your Quartz job. This doesn't really make sense, why don't your just run all of the jobs with Quartz configurations? I don't think this nesting is a good idea.
