Use this: 

 protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
    request.getRequestDispatcher("/login.jsp").forward(request, response);
 }

You have to use a submit input :

<input type="submit" value="Logout">

Make sure the servlet which contains the doPost() method is mapped to logout.java. If not, you have to set the action in your form tag.
