Angularjs post with servlets not working...!

Question

So, This is my view

<div>
    <div class="loginDiv">
        <form name="loginForm" ng-submit="validateDetails()" novalidate>
            <div class="userNameDiv">
                <label class="label" for="username">User Name:</label>
                <input type="text" id="username" name="userName" class="input-medium" ng-model="employee.userName" required ng-minlength=5 ng-maximumlength=20/>
            </div>
            <div class="passwordDiv">
                <label class="label" for="password">Password:</label>
                <input type="password" id="password" name="password" class="input-medium" ng-model="employee.password" required />
            </div>

            <button type="submit" class="btn-large">SUBMIT</button>
        </form>
    </div>
</div>

and the controller to the view is

angular.module('employeeApp.controllers')
    .controller('LoginPageController',['$scope','authenticationDataModelService',function($scope,authenticationDataModelService)
    {

        $scope.validateDetails=function(){
            employee={};
            employee.userName=$scope.employee.userName;
            employee.password=$scope.employee.password;
            console.log(employee);
            authenticationDataModelService.validateData(employee);
        }
    }
    ]);

I am sending this employee object to the service file in which i am sending it in a post request(not including the entire service code):

$http.post(this.employeeDataUrl,employee);

and I am sending it to server and the servlet code is

public class LoginService extends HttpServlet{

    public void doPost(HttpServletRequest request,
            HttpServletResponse response) throws ServletException, IOException {

        PrintWriter printWriter=response.getWriter();
        response.setContentType("text/html");
        String userName = request.getParameter("userName");
        String password = request.getParameter("password");
        EmployeeDAO employee = new EmployeeDAO();
        System.out.println(userName+""+password);
        boolean validateLogin=employee.validateLogin(userName, password);
        if(validateLogin){
            printWriter.println("Login Success");
        }
        else{
            printWriter.println("Login Failed");
        }

    }
}

but i am getting null values here. I am unable to send the values in the employee object from service file in angularjs to the servlet.How could i achieve this??Pardon me if the question is silly...

AngularJS send your "employee" object in JSON, so you can't read this object on server side with your code. You should parse JSON object first.

Yes this is the way to go. Look [here](http://stackoverflow.com/questions/19374345/get-parameter-sent-via-jquery-ajax-in-java-servlet/19376331#19376331) for some more detailed code. It is a similar example (POST object) only using jQuery. – Nikos Paraskevopoulos Nov 07 '13 at 08:58
