今天写了个DWR框架的简单小程序按照书本上写的还是出错了了

we.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5"

dwr.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE dwr PUBLIC
"-//GetAhead Limited//DTD Direct Web Remoting 3.0//EN"
"http://getahead.org/dwr/dwr30.dtd">
<dwr>
<allow>
<create javascript="TestDWR" creator="new">
<param name="class" value="cn.TestDWR"/>
</create>
</allow>
</dwr>

个人写的测试类
package cn;

public class TestDWR {
public boolean check(String name)
{
if(name.equals("lizhichao"))
{
return true;
}else return false;
}
}

引入库DWR.JAR

测试页面index.jsp

<%@ page language="java" import="java.util.*" pageEncoding="ISO-8859-1"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<script type="text/javascript" src="dwr/engine.js"></script>
<script type="text/javascript" src="dwr/util.js"></script>
<script type="text/javascript" src="dwr/interface/TestDWR.js"></script>
<base href="<%=basePath%>">

<meta http-equiv="expires" content="0">
<meta http-equiv="keywords" content="keyword1,keyword2,keyword3">
<meta http-equiv="description" content="This is my page">

<script type="text/javascript">
function checker(bo)
{
if(bo)
{
document.getElementById("c").innerHTML="this name is not used!!!";
}else
{
document.getElementById("c").innerHTML="this name can be used!!";
}
}
function get()
{
TestDWR.check(document.getElementById("name").value,checker);
}
</script>
</head>

<body>
<input type="text" id="name" value="" onblur="get()"/>
<div id="c"></div>
</body>
</html>

用companionjs调试工具来调试就说

TestDWR.check(document.getElementById("name").value,checker);
就说这句没定义

望高手指点一二
