why do i get $http.put().error function displaying

Question

Angular js code

$scope.removeItemFromCart = function (productId) {

$http.put("removeItem/"+productId).success(function() {
    alert("Item Removed");
    $scope.refreshCartItems();
}).error(function(){
    alert("Error");
    $scope.refreshCartItems();
});

};

Rest controller

 @RequestMapping(value = "/removeItem/{productId}", method = RequestMethod.PUT)
   @ResponseStatus(value = HttpStatus.NO_CONTENT)
    public void removeItem (@PathVariable("productId") int productId) {
        System.out.println("Deleting item Id: "+productId);
        CartItem cartItem = cartItemService.getCartItemByItemId(productId);
        cartItemService.removeCartItem(cartItem);

    }

Following is my code for removing an item from my cart. the problem is when i click on remove button in my cart it removes the item but it doesnt enter the success function in my $http.put().success rather show me the error message in the error function of my $http.put().error these functions are in my angular controller. CAn someone tell me what is the problem and where is my error?

Can you tell me the error code and error message that server is returning? — Sachin Gupta, Oct 04 '16 at 06:57
i only get a javascript alert "error" which i have written in the angular js code — NAiVE_developer, Oct 04 '16 at 07:11
in error function you can pass `data, status, header, config` parameters. You can find out error message and other info from these parameters.Or if you can use browser's network tab to get info of rest call — Sachin Gupta, Oct 04 '16 at 07:15

I recommend this

  var req = {
     method: 'PUT',
     url: $consts.base_url + 'removeItem/',
     data: productId,
  };

  req.headers = {
     "content-type":"application/x-www-form-urlencoded", 
     "accept" : "application/json",
     "Authorization" : none
  }

  $http(req).error(function(){
     alert("Error");
  $scope.refreshCartItems();
  }).success(function() {
     alert("Item Removed");
     $scope.refreshCartItems();
  });

If you got error, please let me know the error types in inspect.
