struts 与 jquery ext的一个问题(急啊。谢谢了)

大家好，
我有一个问题一直很纳闷，
用到了struts2, jquery,ext,velocity
先将代码贴出来，然后再叙述问题所在。
web.xml如下：<?xml version="1.0" encoding="UTF-8"?>
<web-app id="WebApp_ID"
 version="2.4"
 xmlns="http://java.sun.com/xml/ns/j2ee"

struts.xml如下：<!DOCTYPE struts PUBLIC
    "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
    "http://struts.apache.org/dtds/struts-2.0.dtd">

<result name="input" type="velocity">/page/login/login.vm</result>
</action>    </package>
</struts>home.vm如下：<HTML>

</HTML>package cn.study.action;import java.util.ArrayList;

private String pwd; public String execute() { if ("cc".equals(name)) {
if ("c".equals(pwd)) {
    return SUCCESS;
} 
}
return INPUT;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public void setPwd(String pwd) {
this.pwd = pwd;
}
}问题如下：
如果我直接访问http://localhost:8080/misDemo/page/login/home.vm 那么home页面就可以正常显示ext所画的面板，
如果我通过登录，struts2的action跳转，则home页面就不能显示ext所画的面板（http://localhost:8080/misDemo/loginAction.do）。
在firefox中运行，说是jQuery未被定义，jQuery is not defined。拜托各位了，我搞了一天，也没想出来原因所在。等待中
