Answer 1

My take on it would be that Web Service defines higher level abstraction such as some business specific functionality. While Servlet is just a software implementation component responsible for transport of data.

Web Service implementation would typically rely on servlet for receiving data. However, it can as well use it's custom layer of dealing with protocol data.

@Controller is probably more related to Web Service than servlet which is,again, a way to implement transport.
