Controller response gets status 406

[Mike Krichevsky]

I have a jQuery function that finds user in database by login and prints the result. But i always get error: and can't figure out why. Any help please?

jQuery

function editUser(login) {
$.ajax({
    type: "post",
    url: "/edit",        
    async: false,
    data: "login=" + login,
    dataType: "json",
    success: function (resp) {
        alert('Success');
    },
    error: function(resp) {
        alert('Fail');
    }
})
}

Controller

@RequestMapping(value="/edit", method=RequestMethod.POST)
public @ResponseBody
Wrapper edit(@RequestParam String login) {
    Wrapper wrapper1 = new Wrapper();
    wrapper1 = wrapper.wrap(userService.findByLogin(login));
    return wrapper1;
}

Firebug

responseText    The resource identified by this request is only capable of generating responses with characteristics not acceptable according to the request "accept" headers.
status          406 
statusText      "Not Acceptable"
