Amit Patel commented on CAMEL-5312:
-----------------------------------
I wrote a Grails application. I don't know how to send this application to you.
In this application, I can add route using Controller. I found issue in
org.restlet.ext.spring.SpringServerServlet it only call createServer method on
it first request. so
I extend the SpringServerServlet and call createServer method when new route is
added. Please find this Servlet in attachment.
Improvement: If component store isNewRoute added variable and ServerServlet
reset this variable i don't need isNewRouteAdded method, so i can gain
performance.

> Project: Camel

> Adding Restlet routes with relative paths to Apache Camel context does NOT
> work after I send first request to restlet route.
> 1) Add Restlet route restletRoute1 with relative path to Apache Camel context
> 2) Send a request to restletRoute1 (works)
> 3) Add a route restletRoute2 with relative path to Apache Camel context
> 4) Send a request to restletRoute2 (does not works). RestletServlet
> does not find the restlet endpoint and return Not Found message.
> when I checked jconsole It saw the restletRoute1 and restletRoute2 started
> successfully. If I add restletRoute1 and restletRoute2 then send a
> request to restletRoute1 and restletRoute2 both works. Our
> application supports add route on-the-fly feature, so we don't have
> to start the application every time when we add a new route. Because of
> the above issue we can't integrate restlet to our application.
