Need cron expression to run job on 1pm,6pm and 11pm

[krishna bala]

I am using the below cron expression to execute the spring job. But it is not working.

0 0 13,18,23 * * ?

Please help me on it.

Not really a Spring question.. Moving to Linux forum

Interestingly, Quartz Scheduler also uses such cron triggers. I'm not sure if that is what you are referring to also or if you are referring to some other framework's triggers. If it is Quartz Scheduler you're referring to, then you might find this page quite helpful.

And if that link doesn't help, then try this link: ItDoesntWorkIsUseless and then post a follow-up based on that.

I think you set the wrong fields -- that looks like a crontab line for running a job at midnight on the 13th, 18th, and 23rd, day of the month.

Thanks for your quick reply.

0 17,18,19 * * * ? , will it work?

Careful now. Spring scheduler expressions look like cron expressions, and they serve the same purpose, but their syntax is different in a very confusing (stupid, IMO) way. Specifically, the columns do not have the same meaning.

Cron (https://en.wikipedia.org/wiki/Cron#Format) :

minute hour dayOfMonth month dayOfWeek

Spring scheduler (http://javahunter.wordpress.com/2011/05/05/cronscheduler-in-spring/) :

Seconds Minutes Hours DayOfMonth Month DayOfWeek Year

Just as an FYI, I entered this conversation via the Linux forum -- so, I am definitely not answering this in regards to Spring.

The expression in Krishna's first post looks OK to me - so he needs to tell us what actually happened, like Paul said. When does this expression fire (which I assume he has tested by now)?

Thanks for your reply.
I will expalin my exact requirement here.

I am using spring Quartz to run my job.

job should trigger at 1pm,6pm and 11pm.

Can any one provide cron expression for it?

I am using following expression to run my job. but job is not triggering.

<bean id="sampleTrigger" class="org.springframework.scheduling.quartz.CronTriggerBean">
<property name="jobDetail" ref="sampleTransactions"/>
<property name="cronExpression" value="0 0 13,18,23 * * ?"/>
</bean>

quick reposne will appriciate , thanks in advance

If it doesn't trigger at the times you desire, when does it trigger? You should be logging the times so that you can look it up later. If it doesn't trigger at all, maybe there's something else wrong with your Spring config.

Thanks for your reply.
it is workign fine in linux not in windows.
it might be due to timeformat issue. In my linux server time format is 24hh , in windows it s 12hh

Thanks a lot.

[Ulf Dittmer]

Interesting. Does it trigger correctly for times before noon?

As a side note, on my Windows, the cron expression for that one is

"0 0 13,18,23 ? * MON,TUE,WED,THU,FRI,SAT,SUN".

I'm using Quartz Scheduler library 2.1.x.

I think "0 0 13,18,23 ? * *" should also work.
