Error!

I'm sorry, but I cannot find a page that matches
<%= request.getAttribute("javax.servlet.forward.request_uri") %>
on the system. Maybe you should try one of the following:

• Go to the server's home page.
  
• Search for relevant pages.
  
  
  
  
  Keywords:
  
  
  
  
  
  
• Admire a random multiple of 404:
  <%= 404*((int)(1000*Math.random())) %>.
  
• Try the amazing and amusing plinko.net
  404 archive.
  

2.9 Designating Pages to Handle Errors 75
The exception-type Element
The error-code element handles the case when a request results in a particular
HTTP status code. But what about the equally common case when the servlet or JSP
page returns 200 but generates a runtime exception? That??™s the situation that can be
handled by the exception-type element.
