Question

当我尝试使用requestDispatcher时，它不转发URL。我检索到这个奇怪的错误

PWC6199：生成的servlet错误：源值1.5已过时，将在以后的版本中删除

PWC6199：生成的servlet错误：目标值1.5已过时，将在以后的版本中删除

PWC6199：生成的servlet错误：要禁止显示有关过时选项的警告，请使用-Xlint：-options。

我尝试使用sendredirect但没有成功。有什么问题？

我的简单servlet MyServletSennesal是：

'import com.senesal.moustac.Utilisateur;
 import java.io.IOException;
 import java.io.PrintWriter;
 import javax.servlet.RequestDispatcher;
 import javax.servlet.ServletException;
 import javax.servlet.annotation.WebServlet;<
 public class MyServletSennesal extends HttpServlet {    
 protected void processRequest(HttpServletRequest request, 
 HttpServletResponse response)
        throws ServletException, IOException {       
    response.setContentType("text/html;charset=UTF-8");        
    System.out.println("Je suis dans la servlet sennesal");
    HttpSession unesession = request.getSession(true);
    String prenom = request.getParameter("txtprenom");
    String nom = request.getParameter("txtnom");
    Utilisateur usn = new Utilisateur(prenom, nom);
    unesession.setAttribute("utilisateur", usn);

    System.out.println("le User est ----->"+usn);
    System.out.println("La session est ----->" +unesession);
    String myurl="/WEB-INF/PageError.jsp";
    RequestDispatcher rd; 


    if(unesession!=null){                    
    myurl="/WEB-INF/bienvenue.jsp";            
    System.out.println("Premiere conditionnelle");
    System.out.println("L'url --->" +myurl);
    //getServletContext().getRequestDispatcher(myurl);       
    rd= request.getRequestDispatcher(myurl);
    rd.forward(request, response);        
    //response.sendRedirect(myurl);
    }else{
        System.out.println("Seconde conditionnelle");
        //getServletContext().getRequestDispatcher(myurl).include(request, response);
        rd= request.getRequestDispatcher(myurl);
        rd.forward(request, response);

    }

我的课程User aka Utilisateur

'package com.senesal.moustac;
 public class Utilisateur {

 private String strprenom;
 private String strnom;

 public Utilisateur() {
 }
  public Utilisateur(String strprenom, String strnom) {
    this.strprenom = strprenom;
    this.strnom = strnom;

 public String getStrprenom() {
    return strprenom;
