How to pass instance variables into Quartz job?

Question

I wonder how to pass an instance variable externally in Quartz?

Below is pseudo code I would like to write. How can I pass externalInstance into this Job?

Answer 1

While scheduling the job using a trigger, you would have defined JobDataMap that is added to the JobDetail. That JobDetail object will be present in the JobExecutionContext passed to the execute() method in your Job. So, you should figure out a way to pass your externalInstance through the JobDataMap. HTH.
