Hello I start to work with comet and as my first step I download GF Source
Edition 3.1.1 (build 12).
After I download the sample app at
/maven/2/com/sun/grizzly/samples/grizzly-comet-hidden/ version 1.9.9
Enabled comet support on GF console (both for default and server
configurations )
Start application in Firefox and IE8.
On firefox I see only the index ,without any number and on IE I see a blank
page (404 )
GF console ,into netbeans 7.01, report :
AVVERTENZA: Response Error during finishResponse
java.lang.NullPointerException

Then what is the problem, and where I can find the source of this
application or other application to study Comet ?
Thanks
