第一次用struts，但是web.xml好像就有问题，请高手指教！

Question

<servlet>
<servlet-name>action</servlet-name>
<servlet-class>org.apache.struts.action.ActionServlet</servlet-class>
<init-param>
<param-name>config</param-name>
<param-value>/WEB-INF/struts-config.xml</param-value>
</init-param>
<init-param>
<param-name>debug</param-name>
<param-value>3</param-value>
</init-param>
<init-param>
<param-name>detail</param-name>
<param-value>3</param-value>
</init-param>
<load-on-startup>0</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>action</servlet-name>
<url-pattern>*.do</url-pattern>
</servlet-mapping>

Answer 1

你的servlet配置有误,
servlet标签中要有servlet-name标签和servlet-class标签，并且servlet标签中的servlet-name标签的值要跟servlet-mapping标签中的servlet-name标签的值一样，楼上的配置是对的。
      

Answer 2

<servlet> 
 <servlet-name>action </servlet-name>
<servlet-class>类名</servlet-class>

  </param-value> 
    </init-param> 
</servlet> <servlet-mapping> 
    <servlet-name>action </servlet-name>
