请问各位大神，ExtJS 4.1 的JS 文件非常多，请问是不是在项目中只需要导入 ext-all.css , bootstrap.js , ext-lang-zh_CN.js 就行了呢？对于这三个文件的存放位置有没有特殊要求？

Ext.onReady(function({
Ext.MessageBox.alert("Ext titel","Ext already load");
});
</script>
</head>

</html>
代码如上，WebRoot下有ext4.1目录，里面就有3个文件ext-all.css,bootstrap.js,ext-lang-zh_CN.js 为什么
该段代码运行后无法弹出Ext的消息窗口呢？仅仅只有 This is my JSP page 几个单词，求教育
