What you have above in the route is an event driven consumer
http://camel.apache.org/event-driven-consumer.html
It triggeres when an event occurs, such as a new jms message arrives.
As such scheduling this is not really easy as it kinda "listen all the time".
To have better control with this you can use polling consumer instead
http://camel.apache.org/polling-consumer.html
And you can combine this with the camel-quartz component to scheduled
using cron syntax
http://camel.apache.org/quartz.html
Or the regular JDK timer
http://camel.apache.org/timer
See the "timer based polling consumer" here
http://camel.apache.org/polling-consumer.html
