下面是dwr的配置信息：
<servlet>
<servlet-name>dwr-invoker</servlet-name>
<servlet-class>uk.ltd.getahead.dwr.DWRServlet</servlet-class>
<init-param>
<param-name>debug</param-name>
<param-value>true</param-value>
</init-param>
<init-param>
<param-name>crossDomainSessionSecurity</param-name>
<param-value>false</param-value>
</init-param>
</servlet>
<servlet-mapping>
<servlet-name>dwr-invoker</servlet-name>
<url-pattern>/dwr/*</url-pattern>
</servlet-mapping>
</web-app>
3，寫服務器端的代碼：（javabean）
4，配置dwr.xml:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE dwr PUBLIC
"-//GetAhead Limited//DTD Direct Web Remoting 2.0//EN"
"的頭文件很重要。
<dwr>
<allow>
<create creator="new" javascript="Hello"> //javabean的方法。
<param name="class" value="org.wll.www.bean.Hello" />//這里與javabean的包相對應。
</create>
</allow>
</dwr>
再就是web頁面的調用。
<html>
<head>
<base href="<%=basePath%>">
<title>dwr實例</title>
<script type='text/javascript' src='/TestDwr/dwr/interface/Hello.js'></script>
<script type='text/javascript' src='/TestDwr/dwr/engine.js'></script>
<script type='text/javascript' src='/TestDwr/dwr/util.js'></script>
<script type='text/javascript' src='hello.js'></script>//這個js是自己寫得一個方法。（下面有 hello.js）
</head>
<body>
<input id="user" type="text" />
<input type='button' value='你好' onclick='hello();'/>
<div id="result"></div>
</body>
</html>
hello.js:
function hello(){
var user = $('user').value;
Hello.checks(user, callback);
}
function callback(msg){
if (typeof window['DWRUtil'] == 'undefined')
{
window.DWRUtil = dwr.util;
}
DWRUtil.setValue('result', msg);
}
