Re-run same job with different parameters when launched via Quartz

[narramadan]

Hi,

I tried the Quartz Example from the samples. As stated in documentation, the job gets executed the very first time and throws 'JobInstanceAlreadyCompleteException' when launched the next time.

But I need to run the job with different parameters when the job is launced via Quartz.

I followed the instructions on configuring incrementer on <job> as specified in chapter-4 Configuring and Running Job (4.5.4 JobParametersIncrementer)

Modified footBallJob.xml, used the incrementer.

<beans:bean id="dynamicJobParameters" class="org.springframework.batch.sample.common.DynamicJobParameters" />  

<job id="footballJob" incrementer="dynamicJobParameters">
	.....
	.....
</job>

Now launched the quartz sample using 'JobRegistryBackgroundJobRunner' as specified. But I still get the below exception

org.springframework.batch.core.repository.JobInstanceAlreadyCompleteException: A job instance already exists and is complete for parameters={}.  If you want to run this job again, change the parameters.

Why does the job not using the incrementer ? Am I missing any other configuration ? Please suggest.

Hi,

I tried with modifying org.springframework.batch.sample.quartz.JobLaunche rDetails getJobParametersFromJobMap() method.

private JobParameters getJobParametersFromJobMap(Map<String, Object> jobDataMap) {
	JobParametersBuilder builder = new JobParametersBuilder();
	builder.addDate("schedule.date", new Date());
	return builder.toJobParameters();
}

The job gets new parameters when launced by quartz. Now am able to re-run the same job with different parameters when launced by quartz.

But why this sample didn't work with an incrementer set for the job ??
