You end up with 2 jetty servers.
When you do
from(jetty) in a Camel route, then that becomes the server.
So instead dont start the Jetty server, but only Camel.
And then from a web browser hit that url
On the other hand if you want Camel to call an external http service, then you should use the http component.
camel-jetty consumer will start a new Jetty server when the consumer is stared.
If you want to leverage a web container to manager the http services, you may consider to use the camel-servlet component.
