Servlets and web components

In this section, we begin the study of web components present in Java EE 7 and supported by WildFly 10, starting from the servlets. Let's start with a simple example of a servlet:

@WebServlet("/SimpleServlet")
public class SimpleServlet extends HttpServlet {
   @Override
   protected void doGet(HttpServletRequest request, HttpServletResponse                      response) throws ServletException, IOException   
   {
      response.getWriter().print("my GET");
   }
   @Override
   protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException  
   {
 response.getWriter().print("my POST");
   }
}

This servlet represents two HTTP methods, GET and POST, represented by the doGet and doPost methods inherited by the javax.servlet.http.HttpServlet abstract class.
