title: Best Java framework for server side WebSockets
body: <p>I want to create simple server having low load. The goal is to give a few javascript clients access to some functionality implemented in Java through WebSockets. I seek for best library to use for that - it should be simple, robust etc. Now I consider 3 alternatives
  - jWebSocket 
  - jetty
  - netty
  What is the best? Or may be something else?</p>
  
  <p>Thanks in advance</p>
