Method Detail

execute

void execute(JobExecutionContext context)
      throws JobExecutionException

Called by the Scheduler when a Trigger fires that is associated with the Job.

The implementation may wish to set a result object on the JobExecutionContext before this method exits. The result itself is meaningless to Quartz, but may be informative to JobListeners or TriggerListeners that are watching the job's execution.

Throws:

JobExecutionException - if there is an exception while executing the job.
