Answer 1

var JSONObject= {"uname":uname, "password":password };
var jsonData = JSON.parse( JSONObject );    

var request = $.ajax({
  url: "rest/orders",
  type: "POST",
  data: jsonData,
  dataType: "json"
});        

Answer 2

Problems with your code:

• .value is a property not an function
• You want to pass json use data of $.ajax
• There no data type as Jsondemo you have to use JSON
• if response data is not JSON you can use $.parseJSON to convertit to JSON

Complete Code

$(document).ready(function(){  
    $('#ok').click(function(){  
        var uname = document.getElementById("uname").value;
        var password = document.getElementById("pwd").value;
        var JSONObject= {
             "uname":uname,
             "password":password
             };

        $.ajax({  
            url:'http://localhost:8090/LoginAuthRWS/rest/orders',  
            type:'post',
            data :  JSONObject,      
            dataType: 'JSON',
            success: function(data) { 
                     var jsonData = $.parseJSON(data); //if data is not json
                     $('#name').val(jsonData.name);  
                     $('#email').val(jsonData.email);  
                }  
        });  
    });  
});
