title: How to customize JBoss AS7 404 page
body: <p>I already created a custom 404 page inside my web app deployed in JBoss AS 7.1. 
  So if my app is at fubar dot com :8080/Myapp and I go to fubar dot com :8080/Myapp/xyzzy, I get the custom error page (defined in the web app's web.xml file).</p>
  
  <p>However, when I go to fubar dot com :8080/xyzzy, JBoss displays the default 404 page which discloses that it's JBoss and which JBoss version.</p>
  
  <p>I need to replace this page in order to hide this information.</p>
  
  <p>Please advise.</p>
