有懂dhtmlxtree树的吗？

Question

jsp页面中有以下代码：
<div id="tree_div" style="width:100%;height:100%"></div>
<script type="text/javascript">
tree=new dhtmlXTreeObject("tree_div","100%","100%","0");
......
tree.loadXML("tree.xml");为什么实际运行中dhtmlXTreeObject装载不进去，错误控制台显示dhtmlXTreeObject is not defined

Answer 1

没有引入dhtmlXTreeOjbect的js文件或者引入文件的路径不正确.

Answer 2

 <link rel="STYLESHEET" type="text/css" href="dhtmlxTree/codebase/dhtmlxtree.css">
<script  src="dhtmlxTree/codebase/dhtmlxcommon.js"></script>
<script  src="dhtmlxTree/codebase/dhtmlxtree.js"></script>
这个应该不会写错的啊！
