jsp页面
//显示用户信息
Ext.QuickTips.init();
var cm = new Ext.grid.ColumnModel([
{header: '用户账号', dataIndex: 'id'},
{header: '用户姓名', dataIndex: 'username'},
{header: '用户密码', dataIndex: 'password'},
{header: '年龄', dataIndex: 'age'},
{header: '生日', dataIndex: 'birthday'},
{header: '地址', dataIndex: 'address'},

]);
var store = new Ext.data.Store({
proxy: new Ext.data.HttpProxy({url:'ListUsersAction'}),
reader: new Ext.data.JsonReader({
totalProperty: 'totalCount',
id:'id',
root:'list'

{id:'id',name: 'id',mapping:'id'},

var grid = new Ext.grid.GridPanel({
renderTo:document.body,
autoHeight: true,
store: store,
width:800,
height:400,

emptyMsg: "没有记录"

});
store.load({params:{start:0,limit:20}});
grid.render();
下面是后台的action:
package ssh.cn.com.action.users;
import java.util.Map;

import ssh.cn.com.service.UsersService;

public class ListUsersAction extends ActionSupport {
private UsersService service;
public UsersService getService() {
return service;
}
public void setService(UsersService service) {
this.service = service;
}
@SuppressWarnings("unchecked")
@Override
public String execute() throws Exception {
Map request = (Map) ActionContext.getContext().get("request");
request.put("list", service.findAll());
return SUCCESS;
}

struts.xml:
<package name="default" namespace="/" extends="json-default">
<action name="listUsersAction" class="ListUsersAction">
<result type="json" />
</action>
</package>
需要用到jsonplugin.jar 这个包
详细的可以参照这个:

不行啊,按你说的配置了以后,直接就报错了。 我的QQ:158704426
详细聊。
追答
报的什么错?struts2+Extjs我是很早之前用过一点,后来觉得不太好,换成了dwr+Extjs了,dwr配合Extjs比较好用。
你好好看下我给你发的那个连接,你按那上面说的弄就差不多,前台这块你可以参照我这个回答:http://zhidao.baidu.com/question/175540962.html
总之,你前台索要的url,就是struts2配置的action,而这个action所返回的就是组织好的json
