Answer 1

Now you can switch to servlet 3.0. It's really simple.

@WebServlet("/example")
public class AnnotationServlet extends HttpServlet{

    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        PrintWriter prinOut = response.getWriter();
        prinOut.write("Hello, This is the first servlet 3 annotation example");
    }

}
