scheduling a service

I've got a service that loads a bunch of data on startup, and I want it
to reload the data every so often. So I implemented the Schedulable
interface, and I want to use the Quartz Scheduler service to execute the
reload. All the examples I've found use a ModelRequest to set the
scheduling parameters...is there any way to set up the scheduled job
within my service when it starts up (my service also implements
initializable, so I'd like to schedule the job inside the initialize
function)?
 
Thanks,
Lou
