This is making me crazy - am trying to integrate a custom Auth bean and i am getting this a null pointer error when i reference my autowired auth manager.

the null pointer is thrown at:
Authentication result = authenticationManager.authenticate(request);


my bean



my app context:
[COLOR=#000080][/COLOR]


The bean must see AM in my context because if i change the alias of the AuthenticationManager in my context the app wont compile. please advise....

I don't see the problem either. I know this sounds strange but did you c+p any of the stuff in the code below? If you did delete those pieces and re-type it out. I have had weird stuff like this happen to me when I have copied stuff into eclipse from a different place. It looks exactly the same but re-typing it makes it work
