Simple and very useful !!

There was a post on the Official Googleblog about fixing broken links on your page.

Eventhough this sounds very trivial, it is often forgotten.

Here is a short guide on how to use it in your (Java/J2EE/JEE) Webapplication.

• Create your 404.jsp (copy it from the index.jsp) with the following header:     
  

  
    <%@ page language="java" isErrorPage="true" %>
  

• Find the location where you want to show this Google error message.
  
• Put the following code on that spot: 
  
  

  
     <style type="text/css"/>
       #goog-wm{}
         #goog-wm h3.closest-match{}
         #goog-wm h3.closest-match a { }
         #goog-wm h3.other-things { }
         #goog-wm ul li { }
         #goog-wm li.search-goog { display:block;}
         </style>
         <script type="text/javascript">
           var GOOG_FIXURL_LANG='nl';
           var GOOG_FIXURL_SITE='http://www.google.com';
          
         </script>
         <script type="text/javascript" src="http://linkhelp.clients.google.com/tbproxy/lh/wm/fixurl.js"></script>
   

  
  



• Add the following code to your web.xml (the errorhandling for Java/J2EE/JEE apps in webapps)
  

  
     <error-page>
         <error-code>404</error-code>
         <location>/404.jsp</location>
     </error-page>
  
     <error-page>
    <exception-type>PageNotFoundException</exception-type>
    <location>/404.jsp</location>
     </error-page> 
  
  

  
  
  

That's it. You can style it as you want, but since this is just text, it will follow your site style.
