dwr-invoker

org.directwebremoting.servlet.DwrServlet

debug

dwr-invoker

3. 写服务端代码(写类)

如:

package com.sk.dwr;

public class Test {

//返回一般数据

public String getString(String s){

return s+"Hello";

}

//返回对象

Public String getUser(String name){

Return new User(name);

}

}

4. 于web.xml同目录下添加并配置dwr.xml
