1.  导入包：dwr.jar，github下载链接：[https://github.com/zhangliqingyun/jarlist/blob/master/dwr/dwr.jar][https_github.com_zhangliqingyun_jarlist_blob_master_dwr_dwr.jar]
2.  Web.xml中的配置：

<servlet>
    
       <servlet-name>dwr-invoker</servlet-name>
    
       <servlet-class>org.directwebremoting.servlet.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>

3.在web-inf目录下创建的dwr.xml文件：

<?xml version="1.0" encoding="UTF-8"?>
    
    <!DOCTYPE dwr PUBLIC 
    
        "-//GetAhead Limited//DTD Direct Web Remoting 2.0//EN"
    
        "http://www.getaead.org/dwr/dwr20.dtd">
    
    <dwr>
    
    
    
    <allow>
    
    
    
    
    
    
    
    <create javascript="Test" creator="new">
    
    
    
    <param name="class" value="cn.jbit.dwr.test.Test"/>
    
    
    
    <include method="testMethod1"/>
    
    <include method="testMethod2"/>
    
    <include method="testMethod3"/>
    
    <include method="testMethod4"/>
    
    <include method="testMethod5"/>
    
    <include method="testMethod6"/>
    
    <include method="testMethod7"/>
    
    <include method="testMethod8"/>
    
    <include method="testMethod9"/>
    
    </create>
    
    
    
    
    
    
    
    
    
    
    
    <convert match="cn.jbit.dwr.entity.User" converter="bean"></convert>
    
    </allow>
    
    
    
    
    
    <signatures>
    
    <![CDATA[
    
    import java.util.List;
    
    import cn.jbit.dwr.entity.User;
    
    import cn.jbit.dwr.test.Test;
    
    Test.testMethod7(List<User>);
    
    Test.testMethod9(Map<String,User>);
    
    ]]>
    
    </signatures>
    
    </dwr>

4.在JSP页面中引入dwr文件，engine.js、uitl.js为dwr.jar包中自带，自定义的dwr引入格式为：/类名/dwr/interface/实体类名.js

5.在javascript中使用dwr定义的方法：

Test.getAge({callback:function aa(callback){
    
                alert(callback+"callback");     
    
            }
