(more > information about what you can do with such framework can be found here : > http://cometdproject.dojotoolkit.org/, > http://www.tutorialized.com/view/tutorial/Create-event-driven-Web-apps-using-Continuous-and-Reverse-Ajax/27495, > http://www.ibm.com/developerworks/web/library/j-jettydwr/) > When you design a reverse ajax application where you want to use the 'push' > technology at the serverside, you need to use a servlet modified using java > New I/O API (see wiki : http://en.wikipedia.org/wiki/Comet_(programming) for > detailed info). Such modified servlet already exist in > Tomcat/Jetty/Glassfish/Grizzly servers because they have implemented the > comet framework. > Next, in order for a client to be notified (through push technology) that > something happens at the server side, an event listener must be created and > link to the comet API. Every time that an action occurs, the event will send > back the information to the browser. Such technology already works today in > DWR package (Direct Web Remoting), Google/Gears, Flex/BlazeDS and the famous > DojoToolkit. > My proposition is to integrate Camel with Cometd/Bayeux protocol in such a > way that we can work with event published. A event available through bayeux > protocol could be exposed as an endpoint to allow to use it through the > routing. > e.g. > At the camel side, the idea is to use the routing as usual : > from(jms:queue) > to(comet:event) > When a message arrives in the queue, we send it to the cometd:event or > bayeux:event endpoint -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
