1、新建web项目,项目名为dwr

 

2、导入以下jar包:

  dwr.jar、classes12.jar、commons-logging-1.0.4.jar和commons-logging.jar

 

3、在WEB-INF下面新增dwr.xml

    xml中的内容如下:

  

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE dwr PUBLIC "-//GetAhead Limited//DTD Direct Web Remoting 2.0//EN" "http://getahead.org/dwr//dwr20.dtd">
<dwr>
 <allow>

  
 
  <create creator="new" javascript="firstDwr" scope="session">
   <param name="class" value="com.shijiaoyun.dwr.test.DwrTest" />
   <include method="showMessage" />
  </create>
 </allow>
</dwr>

注:

  javascript="firstDwr" 表示页面中引用时的名称

  value="com.shijiaoyun.dwr.test.DwrTest" 表示将要调用的类

  <include method="showMessage" /> 表示将要调用的类中的方法名

4、在web.xml中添加一下内容:

<servlet>
   <servlet-name>dwr-invoker</servlet-name>
   <display-name>DWR Servlet</display-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-invoker</servlet-name>
   <url-pattern>/dwr/*</url-pattern>
  </servlet-mapping>

 

5、页面中引入dwr:

 <script type="text/javascript" src="/dwr/dwr/engine.js"></script>
   <script type="text/javascript" src="/dwr/dwr/util.js"></script>
   <script type="text/javascript" src="/dwr/dwr/interface/firstDwr.js"></script>
