I am trying to invoke system.schedule method. The first parameter is name of the schedule, second is the schedule string and third is the instance of the apex class that implements Schedulable interface.

The schedule string is the following

'58 0 20 12 5 ? 2010'

I get an exception saying System.Exception: trigger must be associated with a job detail

Has anyone encountered this exception before? Any idea where i could be missing? Any help would be appreciated.
