The two that I am aware of are Atmosphere

libraries with somewhat differing feature sets, I think one downside to
CometD is there is no provided GWT client whereas Atmosphere does have a

Many projects have used comet to push data from server to client. This
library seems stable although no changes in almost a year.
Appengine's channel api uses comet, works really well, and is easy to
implement.
IMO, web sockets are more desirable to comet in terms of resource
utilization.

Yes gwt-comet will maintain a streaming based (non-polling) connection

You will just have to write the code to hook together the web service
