Answer 1

<servlet> 
     <servlet-name>CounterServlet</servlet-name> 
     <servlet-class>你的Servlet的包路径</servlet-class> 
</servlet> 
<servlet-mapping> 
     <servlet-name>CounterServlet</servlet-name> 
     <url-pattern>CounterServlet.do</url-pattern> 
</servlet-mapping>JSP提交的时候，action里面写CounterServlet.do就可以了

Answer 2

这句（<url-pattern>CounterServlet.do</url-pattern>）可能要这样吧（<url-pattern>/CounterServlet.do</url-pattern>），你试下？要加斜扛（/）

Answer 3

<servlet>
   <servlet-name>CounterServlet</servlet-name>
   <servlet-class>包名.CounterServlet</servlet-class>
</servlet>
   <servlet-mapping>
    <servlet-name>CounterServlet</servlet-name>
    <url-pattern>/CounterServlet</url-pattern>
</servlet-mapping>URL的时候CounterServlet就代表你的servlet
