我在跟着dwr中文教程編碼的時候老是出現Service未定義的問題，我重複的進行代碼測試終於發現爲自己的類更改三處，
第一處在test.js
如下：function update() {
var name = dwr.util.getValue("demoName");
[color=red]Service[/color].sayHello(name, function(data) {
dwr.util.setValue("demoReply", data);
});
}，第二處在dwr.xml
如下：
<create creator="new" javascript="[color=red]Service[/color]">
<param name="class" value="[color=red]helloworld.Service[/color]"/>
</create>，第三處在text.html中
如下：
<script type='text/javascript' src='./dwr/engine.js'> </script>
<script type='text/javascript' src='./dwr/util.js'> </script>
[color=red]<script type='text/javascript' src='./dwr/interface/Service.js'> </script>[/color]
<script type="text/javascript" src='text.js'> </script>
<link rel="stylesheet" type="text/css" href="../tabs/tabs.css" />
<link rel="stylesheet" type="text/css" href="../generic.css" />
