I have classes which I cannot remove because they are in a scheduled job. When I go to Apex Jobs I should be able to see which job they are in, however I cannot find them. There is no Scheduled Apex type in the list of Scheduled Jobs. Is there another method to finding which Scheduled Jobs a class is part of ?
To see a list of scheduled apex jobs go to Setup->Monitoring->Scheduled Jobs. This list also includes other scheduled jobs, i.e. dashboard/report freshes and analytic snapshots. You can create a list view to just scheduled Apex. The Apex Jobs monitoring section will only list @future and batch methods.
