Need suggestion for Openfire WebClient..!

I have openfire setupp and configured properly.I did installed and tried using SparkWeb Client. But chat users recommend me to come up with nice webchat client which should be without Flash stuffs. I have developers team and finally decided writing own chat client. I had UI team which did prepared good interface. Once Clicked on Rooms they can join and leave. But they are facing issue with cometd which is totally new to them.Hence thye are unable to tackle and proceed since Comtd communication with jetty stuff is totally new to them.

Can anyone suggest a tool working on that based platform?
