  • say(FIZZ, WHEN_FIZZ_FACTOR);
  • say(BUZZ, WHEN_BUZZ_FACTOR);
  • elseSayNumber();

  • Encapsula en componentes la vista
  • Es xml de forma que es editable siempre
  • Basado en estándares = XHTML + JavaScript + JSP + Java (JEE5+)
  • Algunas librerías (oracle-ADF, richfaces, icefaces) permiten el desarrollo de Rich Inernet Applications
