How to understand param-values in servlet?

<servlet>
  <servlet-name>moReceiver</servlet-name>
  <servlet-class>hms.kite.samples.api.sms.MoSmsReceiver</servlet-class>

  <init-param>
    <param-name>smsReceiver</param-name>
    <param-value>com.devsapce.samples.sms.FeedbackListner</param-value>
  </init-param>
</servlet>

what is implied by "com.devsapce.samples.sms.FeedbackListner" ? If I copy this and paste this in my web.xml file how should I change this ? I do not have a folder or any such as "devspace/samples/sms". I have stored files in "C:\Users\nser\workspace\cofeeshop". How should I change "com.devsapce.samples.sms.FeedbackListner" ?
