dwr 上使用json10

最近使用dwr传递json数据，dwr说是支持dojo，但是不明白这里的东西。希望有懂这方面的牛人不吝赐教，不胜感激！
这是
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 creator="new" javascript="Demo">
<param name="class" value="mlt.test.Demo" />
</create>
<convert match="mlt.test.Demo" converter="bean" />
</allow>
</dwr>

下面是一个测试页面

<html>
<head>
<script type='text/javascript' src='/zxdy/dwr/interface/Demo.js'>
</script>
<script type='text/javascript' src='/zxdy/dwr/engine.js'>
</script>
<script type='text/javascript' src='/zxdy/dwr/util.js'>
</script>

<script type="text/javascript">
var services = new dojox.rpc.Service( {
target : "../dwr/jsonrpc",
transport : "POST",
envelope : "JSON-RPC-1.0",
contentType : "application/json",
services : {
"Demo.sayHello" : {
returns : {
"type" : "string"
},
parameters : [ {
"type" : "string"
} ]
}
}
});

function update() {
var name = dojo.byId("demoName").value;
var deferred = services.Demo.sayHello(name);
deferred.addCallback(function(result) {
dojo.byId("demoReply").innerHTML = result;
});
}

</script>
</head>
<body>
<p>
Name:
<input type="text" id="demoName" />
<input value="Send" type="button" onclick="update()" />
<br />
Reply:
<span id="demoReply"></span>
</p>
</body>
</html>

下面是
web.xml的配置文件

</servlet>

<servlet-mapping>
