Hi,
You can now use Comet or the Bayeux Protocol (cometd) in GlassFish v3
[1]. I didn't yet enabled it by default because it reduce performance a
little when you stress the server, so if you want to try it, just add
(this is temporary):
-Dv3.grizzly.cometSupport=true
or add the cometSupport element domain.xml like it is described in [1].
Thanks
