... who want to write fancy Ajax applications:

• It is 100% Java:
  • no XML (not even a web.xml)
  • no HTML
  • no CSS
  • no DOM
  • no JavaScript
  • no need to know about browser differences
  • use static types, checked at compile-time
  • enjoy full IDE Java support
• It feels like a Swing application, but instead of Swing widgets, you use qooxdoo widgets
• You write a client-side application, that runs in the browser as an auto-generated JavaScript equivalent of your Java code
• You get “war” files, ready to be deployed in your favorite servlet container
