This happens when the classes are not deployed to the app server in your case Jetty, for a quick workarround use tomcat as teh app server and add the jars to the assembly options

Thanks for your response. It seem now that I am getting following error:
It says that it could not instantiate listener and there is typical ClassNotFoundException.
