Answer 1

It is not data that you should use params instead of data tag.

$scope.postData = function() {

 var data = escape(angular.toJson($scope.items));

 $http({
      method: 'POST',
      url: '/StrutsWithAngular/shopingCart.do',
      params: 'cartValues='+data,
      headers: {'Content-Type': 'application/x-www-form-urlencoded'}
   }).success(function(data, status, headers, config) {
        $scope.items = data;
   }).error(function(data, status, headers, config) {
    // alert("Error :: "+data);
   });
};

Using the second try, before posting the data convert scope to json

This can be done either in two ways either using JSON api or Angular api

I used angular.toJson() and I also used escape method for accepting special characters.

Using request.getParameter you can get the value in the sever side. Hope solution helps everybody.

// Second Try

$scope.postData = function() {

     var data = escape(angular.toJson($scope.items));

     $http({
          method: 'POST',
          url: '/StrutsWithAngular/shopingCart.do',
          data: 'cartValues='+data,
          headers: {'Content-Type': 'application/x-www-form-urlencoded'}
       }).success(function(data, status, headers, config) {
            $scope.items = data;
       }).error(function(data, status, headers, config) {
        // alert("Error :: "+data);
       });
};

Angular does not POST form data, it transmits a JSON object to the server. For information on JSON itself, see JSON.org. There are also a wealth of libraries listed on that page (towards the bottom) that let you parse JSON in various languages, including Java. Not being a Java developer, I can't say that one of them is better than the other, but you should be able to get a good idea of suitability by reading the docs on each one.
