exjs 访问后台数据问题

proxy=new Ext.data.HttpProxy( {url:getContext() + 'findTdepartmentsext.action?
我测试了一下：http://localhost:8080/rms/findTdepartmentsext.action?pages.curPage=0&pages.rowsPerPage=20
成功的返回了xml数据：

• C412AA29_53FF_DE3B_C1AA_C6397311878Effffffff9
• E96FD0E8_8DC8_BB26_1559_BB7CFFFE1C4Bcsccsc8 - 可问题出来了，为什么我解析不了呢，当我把上面的xml文件放到本地却可以解析加载。怎么解决不能直接解析jsp返回的xml？ [b]jsp代码如下：[/b] [code="java"]<%@ page contentType="text/XML; charset=UTF-8"%> <%@ taglib uri="webwork" prefix="ww" %> <?xml version="1.0" encoding="UTF-8"?> /ww:iterator [/code]

[b]departments代码如下[/b]
[code="java"]Ext.onReady(function(){
var proxy=new Ext.data.HttpProxy( {url:getContext() + 'findTdepartmentsext.action?pages.curPage=0&pages.rowsPerPage=20'});

// alert(getContext() + "findTdepartmentsext.action");
// alert(proxy.da);
//store
var store = new Ext.data.Store({
url:'MyXml.xml',
//proxy:proxy,

    reader: new Ext.data.XmlReader({
           record: 'tdepartment'
           //idProperty: 'ASIN',  
           //totalRecords: '@total' 
       }, [
           {name: 'departmentid', mapping: ' departmentid'},
            'departmentname',  'description','sortorder'
       ])
});   

alert(store.getCount());
// grid
var grid = new Ext.grid.GridPanel({
  store: store,
      columns: [
       {header: 'departmentid',width: 200, sortable: true, dataIndex: 'departmentid'},
       {header: 'departmentname', width:200,sortable: true, dataIndex: 'departmentname'},
       {header: 'description', width:200,sortable: true, dataIndex: 'description'},
       {header: 'sortorder', width:200,sortable: true, dataIndex: 'sortorder'}
      ],

     // autoExpandColumn: 'company',
      height: 400,
      width: 840
      //title: 'Marxist_1943'
});
store.load();
grid.render('griddata');
//alert(store.getCount());

});[/code]
着急出结果，哪里没说明白请提问！谢谢大家了

参见：http://www.java2000.net/p8972

既然返回的是xml,就应该使用：
var reader = new Ext.data.XmlReader({
totalRecords: "results",
record: "row",

id: "id"

}, [
{name: 'name', mapping: 'name'},
{name: 'occupation'}

]);
var store=new Ext.data.Store(...{
proxy:proxy,
reader:reader
});
store.load();

也就是说你的：
[color=red]var store = new Ext.data.Store({

url:'MyXml.xml',

//proxy:proxy, [/color]

    reader: new Ext.data.XmlReader({   
           record: 'tdepartment'  
           //idProperty: 'ASIN',     
           //totalRecords: '@total'    
       }, [   
           {name: 'departmentid', mapping: ' departmentid'},   
            'departmentname',  'description','sortorder'  
       ])   
});      

//红色部分有误应为：
var store=new Ext.data.Store(...{
proxy:proxy,
reader:reader
});

明白了，远程的有问题撒，url返回的
http://localhost:8080/rms/findTdepartmentsext.action?pages.curPage=0&pages.rowsPerPage=20
个人认为是他的问题，建议换成
http://localhost:8080/rms/findTdepartmentsext.action?curPage=0&rowsPerPage=20看看能不能解析
