1. 首先需要的jar,如果是maven可以添加如下依赖
<dependency>
<groupId>org.directwebremoting</groupId>
<artifactId>dwr</artifactId>
<version>2.0.1</version>
</dependency><servlet>
<servlet-name>dwr-invoker</servlet-name>

<param-value>java.lang.Object</param-value>
</init-param>
<init-param>
<param-name>debug</param-name>
<param-value>true</param-value>

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