Well, maybe it's because our web app was missing the
<async-supported>true</async-supported> element? Sigh.
Besides adding this in, do I need to do anything else? I've set these
values to true, but with very brief testing it doesn't appear to make
a difference:
asadmin set configs.config.server-config.network-config.protocols.protocol.http-listener-2.http.comet-support-enabled=true
asadmin set configs.config.server-config.network-config.protocols.protocol.http-listener-1.http.comet-support-enabled=true
I get a warning and stack trace the 1st time ICEPush tries to update,
but after that it looks like things are working (though I haven't
tested fully). The stack trace is below. Can you tell me if anything
looks familiar there? I know ICEPush != GF, but you know a lot more
about the Grizzly/web stack than I do. :)
Also, do I need to enable Comet support or not as written above?
Thanks,
Bobby
