Hello,
I was trying to deploy and run the hidden servlet comet example on
glassfish v3 server. I downloaded the grizzly-comet-hidden-1.9.9.war
file from the maven repository. After i deployed the web application, i
navigated to the URL in two different browser (firefox and seamonkey)
and press the click button few times. I am getting the following error
message in the log file. I don't see the value of the counter on the web
page. Can anyone tell me what may be the problem?
Thanks,
Nachiappan
