extjs 代理 proxy 获取html里面json 的问题

Question

这是extjs的代码
Ext.regModel('User',{
fields:[
{name: 'appeId'},
{name: 'survId'},
{name: 'location'},
{name: 'surveyDate'},
{name: 'surveyTime'},
{name: 'inputUserId'}
]

});
var proxy=new Ext.data.proxy.Ajax({
     type:'ajax',
      url:'survey.html' 
});

//构建Store   
    var store=new Ext.data.Store({
      proxy:proxy,
      model:'User',
      autoLoad: true,
      render:'json'


   });
store.add({appeId:'qwe',survId:'123',location:'123',surveyDate:'s',surveyTime:'s',inputUserId:'s'});
store.sync();
//载入
store.load();
// create the grid
var grid = new Ext.grid.GridPanel({
    store: store,        
    columns: [
        {text: "appeId", width: 60, dataIndex: 'appeId', sortable: true},
        {text: "survId", width: 60, dataIndex: 'survId', sortable: true},
        {text: "location", width: 60, dataIndex: 'location', sortable: true},
        {text: "surveyDate", width: 100, dataIndex: 'surveyDate', sortable: true},
        {text: "surveyTime", width: 100, dataIndex: 'surveyTime', sortable: true},
        {text: "inputUserId", width:80, dataIndex: 'inputUserId', sortable: true}
    ],
    renderTo:'example-grid',
    width:540,
    height:200
});



    这是survey.html
    [{"appeId":"1","survId":"1","location":"","surveyDate":"2008-03-14","surveyTime":"12:19:47","inputUserId":"1","inputTime":"2008-03-14

12:21:51","modifyTime":"0000-00-0000:00:00"}]

值传不过来啊，store.add 自己添加的能显示出来。

你怎么返回的，是通过response.getWriter().println返回的吗
