jCron 1.1 (Windows)
Source: Patrick Clark
jCron is a completely free, powerful, and intuitive Java-based task scheduler for Windows NT/2000 that will run as an NT service and will not die if the user logs out (a common problem in other Windows NT/2000 scheduling applications). It is based on the familiar Unix cron with a time granularity of one minute. Using jCron makes it possible to schedule the invocation of the main method of any Java class with arguments. It will also run Win32 EXEs.
