Methods in javax.servlet.http.HttpServlet

Servlets »on Jan 6, 2013 By Sivateja

As we discussed in the earlier articles, we should extend our servlet class with HttpServlet abstract class in order to get protocol dependent [http] services. When ever we make request to the servlet the following methods will be called automatically by the container.

  • Container first calls public Service() method
  • Public Service() method internally calls protected service method
  • Protected Service() method will internally calling doGet() or doPost() [ i mean doXxx() methods, its depends on the type of http method used by the client ]
  • If the client is not specifying the type of Http method then Http protocol by default consider GET method, so finally the client request is processed at doGet() method
  • In general when we are developing any servlets we must take a user defined class are it must extends HttpServlet and override either doGet() or doPost() or Both.
