How to send an error code using JSP to browser?

Following example shows how a 407 error code is sent to the client browser. After this, the browser would show you "Need authentication!!!" message.

<html>
   <head>
      <title>Setting HTTP Status Code</title>
   </head>
   <body>
      <%
         // Set error code and reason.
         response.sendError(407, "Need authentication!!!" );
      %>
   </body>
</html>

You will receive the following output −

type Status report


message
