[1]:在MyEclipse下创建一个web工程。
[2]:把准备好的dwr2.0.3.jar 拷贝到lib下。
[3]:修改web.xml。
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5"
xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
<display-name>DwrApp</display-name>
<servlet>
<servlet-name>dwr-invoker</servlet-name>
<servlet-class>uk.ltd.getahead.dwr.DWRServlet</servlet-class>
<init-param>
<description>dwr调试</description>
<param-name>debug</param-name>
<param-value>true</param-value>
</init-param>
</servlet>
<servlet-mapping>
<servlet-name>dwr-invoker</servlet-name>
<url-pattern>/dwr/*</url-pattern>
</servlet-mapping>
<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
</web-app>
[4]:在web-inf下建立一个dwr.xml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE dwr PUBLIC
"-//GetAhead Limited//DTD Direct Web Remoting 2.0//EN"
"http://www.getahead.ltd.uk/dwr/dwr20.dtd">
<dwr>
<allow>
<create creator="new" javascript="Hello">
<param name="class" value="test.DwrDemo"/>
</create>
</allow>
</dwr>
[5]:src下建立一个包test,然后建立一个class : DwrDemo
package test;
/**
*
* @author xp E-mail: xipei_1984@163.com
* @version 创建时间：2009-6-19 上午12:01:41
*/
public class DwrDemo {
public String message;
public String sayHello(String message) {
return "大家好:" + message;
}
public String getMessage() {
return message;
}
public void setMessage(String message) {
this.message = message;
}
}
[6]:开始页面了吧：index.jsp
<%@ page language="java" import="java.util.*" pageEncoding="ISO-8859-1"%>
<%String path = request.getContextPath();%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<title>My JSP 'index.jsp' starting page</title>
<script type="text/javascript" src="<%=path%>/dwr/interface/Hello.js"></script>
<script type="text/javascript" src="<%=path%>/dwr/engine.js"></script>
<script type="text/javascript" src="<%=path%>/dwr/util.js"></script>
<!--这三个是dwr自动创建的，注意黑体与下面黑体的区别--->
<script>
function testDwr() {
var hello = document.getElementById("hello").value;
Hello.sayHello(hello, callBackHello);
}
function callBackHello(data) {
alert(data);
}
</script>
</head>
<body>
<input type="text" name="hello"><input type="button" value="submit" onclick="testDwr()">
</body>
</html>
