Trigger start/stop/resume/suspend of a camel route using queue, db
Hi,
Can we extend the RoutePolicy class in Camel to trigger
start/stop/resume/suspend camel route based on an Action which is not based
on events coming from Quartz Jobs but by example messages/events published
in a queue, db, ...
If this is possible, does it mean that the class who will extend the
RoutePolicy must be created into the corresponding camel-component
(camel-jms for messages in queue, camel-jdbc or sql or jpa for messages in a
DB, ....) ?
Regards,
Charles

See this page
http://camel.apache.org/routepolicy
You can then add logic in onExchangeDone and check for failure, and
then react accordingly.
To suspend/stop a route see the next FAQ
See this FAQ
http://camel.apache.org/how-can-i-stop-a-route-from-a-route.html
An alternative is to use an event notifier to listen on events, and
then react accordingly.
http://camel.apache.org/eventnotifier-to-log-details-about-all-sent-exchanges.html
Then you can listen for exchanges failed, and coming from a given
route/endpoint as origin. To know it was from the route you want to
suspend if X number of errors etc.
There is API on CamelContext to control routes, to suspend/stop/start etc.

Hi ,
Can you provide me some sample of camel context which uses suspend and
resume route .
I have requirement to suspend a route ( in a camel-context.xml ) when n
number errors occurred calling a http endpoint and stop consuming messages
from jms queue for x time and resume this route to start consuming messages
from jms queue and send it to http endpoint.
Regards
Raj

Yes thats possible.
I suggest to build custom policy and include that in your Camel application.
Of course there may be some OSGi imports you need because the custom
policy need to use JDBC or whatever to integrate with the DB.
