Wicket-Atmosphere configuration error - wicket

Question

I am new to Atmosphere, I have created a wicket quick start application(6.19.0) and configured Atmosphere but getting following error:
2016-11-09 17:29:31 WARN AtmosphereFramework:1679 - Failed using comet support: org.atmosphere.container.Tomcat7CometSupport, error: Tomcat failed to detect this is a Comet application because context.xml is missing or the Http11NioProtocol Connector is not enabled.You must use the atmosphere-native-runtime dependency in order to use native Comet Support
If that's not the case, you can also remove META-INF/context.xml and WEB-INF/lib/atmosphere-compat-tomcat7.jar Is the NIO or APR Connector enabled?
2016-11-09 17:29:31 ERROR AtmosphereFramework:1682 - If you have more than one Connector enabled, make sure they both use the same protocol, e.g NIO/APR or HTTP for all. If not, org.atmosphere.container.BlockingIOCometSupport will be used and cannot be changed.

And there is no context.xml file. I have removed the comment from following line in server.xml
<Connector port="9443" protocol="org.apache.coyote.http11.Http11NioProtocol"
maxThreads="150" SSLEnabled="true" scheme="https" secure="true"
keystorefile="file:///D:/SSL/keystore" keystorepass="changeit"
clientAuth="false" sslProtocol="TLS" />
Can anyone provide some idea on this?
Thanks in advance.
