Just by equating your question and the numebr of JSPs you have mentioned as well drawn, it is expected to create 3 Servlets.
You should not call those as 'Servlet Files' because there is no such term. Instead you might have asked '
java files' which is quite meaningful.
You have 3 jsp files, and in turn they each would get converted into Servlets. So you get 3 servlets. But when you get all those servlets is not assured as it depends on the request to JSP files and on the container.
