I have supposed to do 4 actions: CreateUser, Modify, View and delete. After deleting the user details, once again if click on ModifyUser or ViewUser im getting NullPointer Exception. Can some one please help me by correcting my code.


index.jsp
<body>
<form>
<a href="NewUser.jsp">New User</a>
<a href="ModifyUser.jsp">Modify User</a>
<a href="ViewUser.jsp">View User</a> 
<a href="DeleteUser.jsp">Delete User</a>
 
<form>
<body>

ModifyUser(Action class)
 
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException
{
  User user = new User();
  User user1 = new User();
 
  HttpSession session = request.getSession(true);
 
  user.setFirstName(request.getParameter("FirstName"));
  user.setLastName(request.getParameter("LastName"));
  user.setUserId(request.getParameter("UserId"));
  user1.setContactNumber(request.getParameter("ContactNumber"));
  user1.setLandLine(request.getParameter("LandLine"));
 
  session.setAttribute("modifiedUserInfo",user1);
  response.sendRedirect("EditedDetails.jsp");
 
  if(session.getAttribute("modifiedUserInfo")==null)
  {
    response.sendRedirect("NoUser.jsp");   
  }
