Unable to run a service command via cron

service service_name start

When i tried running this from cmd line, it works. But when i try to schedule it via cron, i get an error saying

/bin/sh: service: command not found


sbin is not in the path when run via cron. Specify the full path to service. This is probably either /sbin/service or /usr/sbin/service. You can find the path on your system by running which service.
