scheduling a batch job

[gaurav]

Hello,
Can someone provide a sample for scheduling a batch job with Quartz or any other method.

Thanks in Advance

There used to be a Quartz sample job before M2, but it was really much more an example of Spring-Quartz integration rather than anything Spring Batch specific.

If you need something quickly take a look at the Quartz chapter in Spring documentation and it should be mostly a copy-paste issue. Or you can start a Jira issue - I should be able to attach an example file within next week.

Thanks for the reply. I will refer to that document on Quartz and try to implement in batch envirnment.

I have created JIRA issue and the link is
http://jira.springframework.org/browse/BATCH-276

I would be glad if you can suggest an sample code or example.

Here is a sample crontab entry (assuming classpath and beanRefContext are set up properly):

0 6 * * 1-5 java org.springframework.batch.execution.bootstrap.support.BatchCommandLineLauncher -Djob.configuration.path=jobs/myJob.xml -Djob.name=myJob

At 6AM every weekday morning, launch "myJob" from file "myJob.xml"

0 6 * * 1-5 java org.springframework.batch.execution.bootstrap.support.BatchCommandLineLauncher -Djob.configuration.path=jobs/myJob.xml -Djob.name=myJob

At 6AM every weekday morning, launch "myJob" from file "myJob.xml"

Note you need to have classpath configured first and only then you can use the crontab one-liner.
Update: sorry the original entry states that already, overlooked it

Writing a job in Quartz would be the same procedure as the crontab above, only you would use the quartz Native job as your quartz job, with the spring batch command line launcher as it's process to be executed.

You could also use Spring's quartz integration to inject a Spring Batch JobLauncher, although every job launched this way will be in the same jvm.

Here is an example for both local jvm and native job variants:

The QuartzBatchJob class is basicly a copy-paste of BatchCommandLineLauncher#start method - maybe it is worth to extract this logic from the "command line" class?

Which version of Quartz do you have - Spring Core removed supporyt for older versions in the latest release, I believe.
