项目需要引用的jar包，放入WEB-INF/lib目录下
dwr.jar
commons-logging.jar

添加新文件 WEB-INF/dwr.xml
<dwr>
<allow>
<create creator="new" javascript="userDwr">
<param name="class" value="dwr.UserDwr"/>
</create>
</allow>
</dwr>
WEB-INF/web.xml中需要添加servlet
<servlet>
<servlet-name>dwrServlet</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>dwrServlet</servlet-name>
<url-pattern>/dwr/*</url-pattern>
</servlet-mapping>
//测试类
package dwr;
public class UserDwr {
public String say(String content){
return "用户说："+content;
}
}
//根目录下 index.html
