title: How to display a pop up notification to the user using jquery?
body: <p>I am developing an application which requires that user must be notified about some background events i.e. invitation from other user, reminder time out etc. </p>
  
  <p>Whenever the event occurs the controller will be notified, and a small window should be displayed to the user. </p>
  
  <p>How should I proceed to achieve this. Which technology / tool will help me. I am using jQuery, JSF 2.0 and Spring 3.0.</p>
