>Just a note. Do you want the route to trigger *only* when CamelContext has just been started? What if you stop and start the route later, eg using JMX? I wonder if Quartz got some configuration to fire on startup as well? But anyway Stephen showed a great solution later in this mail thread. Also you can just register some spring bean and have it depends on camel and then fire in some messages to the routes you want to get started. But the notification might be a nicer solution as you get fine grained callbacks and can fire upon camel context started etc. > Thanks for any help in unwinding my confusion. > -- > View this message in context: > http://old.nabble.com/Startup-invocation-of-a-route-tp26949232p26949232.html > Sent from the Camel - Users mailing list archive at Nabble.com. > > -- Claus Ibsen Apache Camel Committer Author of Camel in Action: http://www.manning.com/ibsen/ Open Source Integration: http://fusesource.com Blog: http://davsclaus.blogspot.com/ Twitter: http://twitter.com/davsclaus
