我根据http://book.csdn.net/bookfiles/159/1001596837.shtml的内容进行的配置，进行到第四步时在浏览器地址栏中输入http://localhost:8080/ajaxlab/dwr查看部署效果，就出现了如题的错误！请高手指教一下啊！
我的配置如下：
web.xml:
<servlet>
<servlet-name>dwr-invoker</servlet-name>
<servlet-class>uk.ltd.getahead.dwr.DWRServlet</servlet-class>
<init-param>
<param-name>debug</param-name>
<param-value>true</param-value>
</init-param>
<init-param>
<param-name>config-1</param-name>
<param-value>WEB-INF/dwr.xml</param-value>
</init-param>
</servlet>
dwr.xml:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYP
我的配置如下：
web.xml:
<servlet>
<servlet-name>dwr-invoker</servlet-name>
<servlet-class>uk.ltd.getahead.dwr.DWRServlet</servlet-class>
<init-param>
<param-name>debug</param-name>
<param-value>true</param-value>
</init-param>
<init-param>
<param-name>config-1</param-name>
<param-value>WEB-INF/dwr.xml</param-value>
</init-param>
</servlet>
dwr.xml:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYP
<servlet>
<servlet-name>dwr-invoker</servlet-name>
<servlet-class>uk.ltd.getahead.dwr.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-patten>/dwr/*</url-patten>
</servlet-mapping>
是少导入了一个jar包，貌似叫commons-logging.jar的jar包
