<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>   
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>2) Titre : ecrasee par servlet2</title>
</head>
<body> 
<p>2) Par le mappage de cette page jsp et de la servlet MaServlet, il y a ecrasement de ce contenu par a servlet</p>
<p>Pour le vérifier mapper puis démapper par le fichier web.xml sité dans le dossier WebContent</p>
</body>     
</html>

Where is your web.xml ? See my answer and if you have <servlet> and <servlet-mapping> tags remove them from there. — Alexei Petrov

Your anotation is wrong. It should be

@WebServlet(name = "SecondeServlet", urlPatterns = {"/MaSecondeServlet"})

This is your result. App is named Test

Try this code.

package test.servletpac;  

import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import java.io.IOException; 

@WebServlet(name = "SecondeServlet", urlPatterns = {"/MaSecondeServlet"})
public class SecondeServlet extends HttpServlet {
    private static final long serialVersionUID = 1L;       


    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
                    getServletContext().getRequestDispatcher("/secondejspservlet.jsp").forward(request, response);

    }
    protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {    
    }    
}
