Basic Authentication in Spring Security( authentication failure message)

Question

I am developing website(HTML, javascript, jQuery, Ajax, css) in which, I am using basic authentication in spring in server side. I am sending Basic="Base64 Endcoded Username & password" in Authorization header of HTTP request. Login works fine on correct username & password. But on failure, it shows me a default prompt to enter a username & password. What can I do to so that prompt is not shown, Instead I should get a error code. So that, I can display proper failure message.
