Quartz scheduler cron expression not working

Question

I am wondering why this Quartz cron expression isn't working:

<trigger>
         <cron>
            <name>jobtriggername</name>
            <group>groupname</group>
            <job-name>jobname</job-name>
            <job-group>jobgroup</job-group>
            <misfire-instruction>MISFIRE_INSTRUCTION_DO_NOTHING</misfire-instruction>
            <cron-expression>0 0/30 0-6,12,19-23 * * ?</cron-expression>
          </cron>
      </trigger>

When I start the application server the following exception is thrown:

I don't think this is some esoteric cron expression?

Answer 1

Please go through some examples here.

0 0/30 0-6,12,19-23 * * ?

Here 0-6,12,19-23 section seems to be the problem. Try replacing it with

0,1,2,3,4,5,6,12,19,20,21,22,23

Even though some other vendors support complex cron expressions like 0 0/5 14,18,3-39,52 ? JAN,MAR,SEP MON-FRI 2002-2010, I think Quartz does not. If this not works, please give your cron requirement.
