问题
I've got a GWT application, which periodically needs to update the screen with new tick items as they come in. We also have messages published by a CometD/Bayeux server (for a different AJAX application) and I'd like to consume them in my GWT.
Of course, I can drop into JavaScript, hook up Dojo, and receive callbacks in the JavaScript layer - and from there, route a call into GWT Java code via a JSNI - but there doesn't appear to be any support in GWT directly for using long push or async calls other than the non-RESTful RPC.
How have you integrated GWT and Bayeux?

JSNI is not that bad option as it might sound first. There is a DZone refcardz 'GWT: Style, Configuration and JSNI Reference' which I have found helpful.
