    <display-name>CalculatorServlet</display-name>
    <servlet-name>CalculatorServlet</servlet-name>
    <servlet-class>com.ywn.CalculatorServlet</servlet-class>
    <init-param>
    <param-name>sleep.time</param-name>
    <param-value>2000</param-value>
    </init-param>
  </servlet>
  <servlet-mapping>
    <servlet-name>CalculatorServlet</servlet-name>
