Bad Request while passing JSON data to Spring Controller

I refered to the post @ 400 Bad request on Spring Jquery Ajax Post

But I'm still getting a 400 bad request even when I follow the suggestion provided in the earlier post. Can anyone please let me know where am I going wrong.

Controller:

  @RequestMapping(value = "validateLine.htm", method = RequestMethod.POST)
@ResponseBody
public JSONResponse checkForExceptions(HttpSession session,@RequestBody  OrderLine[] lineData) { 

    // do something
}

And AJAX Call

$.ajax({
    type : "POST",
    url : "/order/validateLine.htm",
    data : aData,
    dataType : 'json',
    contentType: 'application/json',
    success: function(response){  
            // do Something
            }
    });

Data sent to server from FireBug

[{"lineId":"2","itemDesctiption":"Item Desc 2","bundleDescription":"Bundle Desc 2"},{"lineId":"2","itemDesctiption":"Item Desc 2","bundleDescription":"Bundle Desc 2"}]

And if I say @RequestBody ArrayList <OrderLine> lineData I get the data as LinkedHashMap and throws an Exception.

Finally I was able to figure out the issue after spending one day. Its a typo :( I was sending lineId from javascript but it my Object class it was lineID (uppercase D).

Thank you all for your time.Appreciate it.

You need to make sure it is returning the right content type:

headers.add("Content-Type", "application/json; charset=utf-8");

Also, while there, should only accept the right content type:

@RequestMapping(headers = "Accept=application/json")
