Sorry for the naive question...if this is in the FAQ please just let me
know.
What happens between the client and server for RAP listener
notifications? For example, if I setup a MouseListener is there
communication between the web client (javascript) and the RAP server
process when the listener is notified with UI events?
Does the implementation (if any) use xmlhttprequest or some such?
Just FYI...might make sense to use a high-performance asynch messaging
(e.g. JMS) rather than strict http xmlhttprequests to implement, for
performance reasons, etc. For example, ECF remote services on JMS:
http://wiki.eclipse.org/index.php/ECF_API_Docs#Remote_Servic es_API
ECF remote services are OSGi services...exposed either as OSGi service
proxies, or via a more explicit messaging interface called
IRemoteService. Can run over multiple transports.
In any event (so to speak :)...

Sure. Note the remote services API is transport agnostic...so one can
use (e.g.) JMS, xmlhttprequest, private protocol, etc...based upon
performance, reliability, and scaling requirements.
ECF is having its 1.2 release tomorrow (Fri Oct 19).
