I also attached the used jars.
I’m appreciated for any advices.

Hi,

For some reason your jetty cannot find the atmosphere servlet class. That class should be in atmosphere-runtime.jar. Maybe some packaging problem. Hard to say more with these details.

cheers,

Hi, Matti:

I think you are right.
I was using Eclipse + RunJettyRun to test my web application.
Now I changed to use Tomcat 6.0.33, and this issue is gone.
Thank you!
