Spring Security Ajax-Anmeldung

Question

Ich habe diesen Sicherheitsprozess in meinem Projekt implementiert: Spring Security 3 - MVC Integration Tutorial (Teil 2) .

Mein Problem ist, dass ich es in ein Ajax-basiertes Login verwandeln muss. Was muss ich tun, um diese XML geeignet mit nur Rückgabe String/JSON an den Client zu machen? Ich verstehe, dass das Problem vielleicht in der form-login Tag.
