📄 dwr实例一.txt
字号:
第一个简单小例子
1，创建AS1项目
2，创建RemoteBean：
public class RemoteBean {
public String getServerDate() {
return new Date().toString();
}
}
3，再CLASSPATH中加入dwr.jar
4，编写web.xml，参见web.xml模板
<servlet>
<description>DWR Servlet</description>
<servlet-name>dwr-servlet</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>
</servlet>
<servlet-mapping>
<servlet-name>dwr-servlet</servlet-name>
<url-pattern>/dwr/*</url-pattern>
</servlet-mapping>
5，编写dwr.xml，参见dwr.xml模板
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE dwr PUBLIC
"-//GetAhead Limited//DTD Direct Web Remoting 1.0//EN"
"http://www.getahead.ltd.uk/dwr/dwr10.dtd">
<dwr>
<allow>
<create javascript="RemoteBean" creator="new">
<param name="class" value="tarena.RemoteBean"></param>
</create>
</allow>
</dwr>
6，将web.xml和dwr.xml文件放在WEB-INF下
7，布署AS1项目成功后，并访问下列地址
http://localhost:8080/AS1/dwr/index.html
出项以下信息表示安装配置DWR成功。

<script type="text/javascript">
function getServerDateTime(){
RemoteBean.getServerDate(handleGetServerDateTime);
}
function handleGetServerDateTime(dateTime){
DWRUtil.setValue("serverDateTime",dateTime);
}
</script>
</head>
<body>
