=3E emerged from a job scheduling consulting project I did in autumn =

=3E 2003=2E We have concrete needs for this now at werk3AT=2C thus the =

=3E revival=3A It=27s about quite simple cron-style scheduling of =

=3E application jobs=2E
=3E =

=3E The basic idea is to set up a Quartz Scheduler via a =

=3E SchedulerFactoryBean=2C also allowing to register scheduled jobs =

=3E there via a =3Clist=3E of =3Crefs=3E to ScheduledJobDefinition beans=2E=
 A =

=3E ScheduledJobDefinition is just a simple combination of a Quartz =

=3E JobDetail and a Quartz Trigger=2E
=3E =

=3E ScheduledJobDefinition bean implementations include=3A
=3E - DefaultScheduledJobDefinition=2C allowing to use any =

=3E implementation of Quartz=27 Job interface with a declaratively =

=3E configured job data map and cron trigger
=3E - MethodInvokingJobDefinition=2C allowing to specify a method of a =

=3E Spring-managed bean to execute as job (completely declarative=2C =

=3E without the need for implementing a custom Job object)=2C with a =

=3E cron trigger=2E
=3E =

=3E Both job definition beans can link in a separate Quartz Trigger =

=3E instance instead of a cron expression=3B =

=3E DefaultScheduledJobDefinition can also link in a separate Quartz =

=3E JobDetail instance instead of a job class=2E
=3E =

=3E That=27s all there is=3A A simple declarative way of using Quartz =

=3E within Spring=2E Typically no rescheduling or the like=3A All =

=3E schedules are set up on context startup=2C defined as bean =

=3E definitions=2E Of course=2C you can also fetch the Scheduler instance=
 =

=3E and perform any custom scheduling=2C instead of using preconfigured =

=3E ScheduledJobDefinition beans=2E
=3E =

=3E The typical usage scenario are low-level jobs within an =

=3E application=2C like data synchronization or storage cleanup - all =

=3E predefined jobs that are just customized by an administrator=2E Fits =

=3E nicely into Spring=27s application context model=3B most jobs will =

=3E simply delegate to Spring-managed business objects=2E
=3E =

=3E I expect to have this polished by the end of the week=2C as we need =

=3E it at werk3AT quite urgently=2E I=27d like to include this already in=
 =

=3E Spring 1=2E0 final=2C as it=27s just 6 pretty simple classes (yes=2C =
I =

=3E know - feature freeze - never mind =3B-)=2E The main question is wher=
e =

=3E to put it=3A I suggest =22org=2Espringframework=2Escheduling=2Equartz=
=22=2E
=3E =

=3E If there are no general objections=2C I=27ll commit it by the end of =

=3E this week=2C for review within the next week - still plenty of time =

=3E before 1=2E0 final =3B-) Looking forward to your feedback! =
