I don't know how much work would be to port your application logic to CometD. Typically it's not a huge work to port only the application logic. By using CometD you would be able to drop a lot of "infrastructure" code that handles the WebSocket details. For example, message relaying among nodes (solved by CometD), node discovery (CometD), node crash detection (CometD), high level API independent from transport (CometD), data distribution (CometD), service forwarding (CometD), and a ton of other features. > or if I can some how add CometD for just the specific problem I am facing on > my Jetty-based > WebSocket application. >From what you describe you seem a bit out of path, as HTTP session clustering is typically not a problem that you need to solve. There is no HTTP if you're using WebSocket, and furthermore even if you rely on that bit of HTTP during the WebSocket upgrade, it won't solve your load balancing issue. You certainly need load balancing sticking based on client IP (connections) for WebSocket. > How do I integrate CometD into my Jetty WebSocket > based webapp? Are there examples out there? That I cannot tell, since you don't describe what your application does. There are plenty of examples in the CometD examples shipped with the distribution (like 4 different chat implementations), or you can borrow from the test suite or, for the distributed chat, the GitHub repository that I linked in an earlier message. The advantage of using CometD is that if WebSocket is not going to work for you (e.g. mobile networks, antiviruses, firewalls, transparent proxies, etc.), you can transparently fallback to HTTP without changing a single line of code. -- Simone Bordet ---- http://cometd.org http://webtide.com Developer advice, training, services and support from the Jetty & CometD experts. _______________________________________________ jetty-users mailing list [email protected] To change your delivery options, retrieve your password, or unsubscribe from this list, visit https://dev.eclipse.org/mailman/listinfo/jetty-users
