I'm trying to get some j son data from a local server using Senchatouch-2 app:

我收到以下消息：

load http://localhost:8084/Sencha/senchatest. Origin http://localhost:8084 is not allowed by Access-Control-Allow-Origin.

Even If I launch my sencha app as an, I get this:

   XMLHttpRequest cannot load http://localhost:8084/Sencha/senchatest.Origin null is not allowed by Access-Control-Allow-Origin

The web service returns data. I try to catch the data items like this:

// 动态列表视图

 proxy:{
            type: 'ajax',
            method:'GET',
            model:'List.model.Mainmodel',
            url: 'http://localhost:8084/Sencha/senchatest',

            reader: {
                type: 'json',
                rootProperty: 'data.firstName.lastName'
              }}  

And I'm trying to get this structure:
   {"data":[{"firstName": "dhina", "lastName": "karan"},{"firstName": "dhina", "lastName": "karan"},{"firstName": "dhina", "lastName": "karan"},{"firstName": "dhina", "lastName": "karan"},{"firstName": "dhina", "lastName": "karan"},{"firstName": "dhina", "lastName": "karan"}]}

你知道我为什么会收到这个错误吗？

谢谢，

问候

确保您已通过服务器获取您的页面，而不是通过文件系统加载它
