我将通过以下示例代码向您解释。

 <servlet>
   <description></description>            // enter description of servlet
   <display-name>GetCascadParamServlet</display-name>  // the name which display in url
   <servlet-name>GetCascadParamServlet</servlet-name>   // Actual servlet name
   <servlet-class>com.agileinfotech.bsviewer.servlet.GetCascadParamServlet</servlet-class> // this is package name , where exactly your servlet locate 
 </servlet>
 <servlet-mapping>
   <servlet-name>GetCascadParamServlet</servlet-name>  // servlet name which exact declare same as your servlet name
   <url-pattern>/GetCascadParamServlet</url-pattern>  // if we want to call another servlet or class we can declare it here when it will see that url redirect it to the that configuration.
 </servlet-mapping>

希望您能够理解servlet的整个映射。
