Class NativeJob

java.lang.Object

org.quartz.jobs.NativeJob

All Implemented Interfaces:

Job

public class NativeJob
extends Object
implements Job

Built in job for executing native executables in a separate process.

             JobDetail job = new JobDetail("dumbJob", null, org.quartz.jobs.NativeJob.class);
             job.getJobDataMap().put(org.quartz.jobs.NativeJob.PROP_COMMAND, "echo \"hi\" >> foobar.txt");
             Trigger trigger = TriggerUtils.makeSecondlyTrigger(5);
             trigger.setName("dumbTrigger");
             sched.scheduleJob(job, trigger);
 

If PROP_WAIT_FOR_PROCESS is true, then the Integer exit value of the process will be saved as the job execution result in the JobExecutionContext.
