1、將dwr.jar放至WEB-INF/lib下面
2、將dwr.xml放至WEB-INF下面
<allow>
<create creator="new" javascript="AddressLookup">
<param name="class" value="zdsystem.AddressLookup"/>
</create>
</allow>
3.在web.xml中添加
<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>
