title: Which is better JETTY COMET implementation or Resin COMET implementation
body: <p>We've been using JETTY's suspended servlet implementation to roll our own COMET  web applications using JSON messages and XStream.</p>
  
  <p>Does anyone have experience with Resin's implementation of COMET and how they compare?</p>
  
  <p>Also more generically than COMET does anyone have suggestions on the best Java Suspended servlet 3.0 implementation.</p>
  
  <p>Here are some resources:</p>
