406 Not Acceptable: Spring 3.2 + JSON + AJAX

Searched tons of sites and even stackoverflow but have not found a solution to this problem. Looks like lot of people have encountered this problem but its seems a unified solution is missing that encompasses all the aspect. Have already spent 1.5 days on it.

I see the method is getting invoked but somewhere @ResponseBody is not getting translated properly. Can someone take a look and let me know what the problem is. I have Uploaded the code on github. Link to source code on github

@RequestMapping(value = "/find_user", method = RequestMethod.GET)
public @ResponseBody List<String> findUser(@RequestParam("term") String name) {
    log.info("Search string for user name: " + name);   
    List<String> users = new ArrayList<String>();
    users.add("Sam");
    users.add("Dan");
    return users;
}

Please note: Ah! How painful. This setup works with Spring 3.1.4 and not with 3.2.X

I also faced up with a same problem. After debugging Spring I found that ServletPathExtensionContentNegotiationStrategy tries to determine media type based on an extension in the URL. (Probably, because it cannot deduce what media type it should return from Accept header which contained */* in my case.)

So, one of the way to fix this is to rename URL in mapping by replacing .html by .json.

God, it almost kills me. I tried whatever I can, still stuck there. But finally I figured it out. The reason is Spring, download Spring 3.1.1 and replace all the jars with 3.1.1jars, and it works. All your config is good.
