404 error while redirecting to html from a servlet












0















I have a problem with a school project, it's a little web dinamic project.
In the Login page, if I submit parameters of a user that exist in my DB, all goes well and I have my "success.html" page, but if I submit parameters of a user that is not in my DB I have a 404 page, while I'm expecting my "failure.html".
Could u please help me to find the error?



I'm using:




  • Eclipse Java Neon

  • Tomcat 9.0.12


This is my login form: 



<form id="login" class="form-horizontal" action="/IROPLAS/Controller/LoginServlet" method="GET">

            <div class="form-group">

                <label class="control-label col-xs-8 col-sm-4 col-md-5" for="mail">E-mail:</label>

                <div class="col-xs-10 col-sm-8 col-md-4">

                    <input type="text" class="form-control" id="mail" name="mail" placeholder="E-mail">

                </div>

            </div>

            <div class="form-group">

                <label class="control-label col-xs-8 col-sm-4 col-md-5" for="pw">Password:</label>

                <div class="col-xs-10 col-sm-8 col-md-4">

                    <input type="password" class="form-control" id="pw" name="pw" placeholder="Password">

                </div>

        </form>


This is my Servlet:

    public LoginServlet() {

    }



    /**

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

        response.getWriter().append("Served at: ").append(request.getContextPath());

        response.setContentType("text/html");



        RequestDispatcher requestDispatcher; 

         String m=request.getParameter("mail");  

         String p=request.getParameter("pw");  



         if(Model.BUtente.validate(m, p)){

             Model.BUtente u=Model.BUtente.getUtente(m, p);          

             request.setAttribute("utente", u);

             requestDispatcher=request.getRequestDispatcher("/Success.html");

             requestDispatcher.forward(request, response);

         } //pagina profilo utente

         else{       

             PrintWriter pw=response.getWriter();

             response.sendRedirect(request.getContextPath()+"/Failure.html");            

             pw.close();

         }//errore





    }



    /**

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

        // TODO Auto-generated method stub

        doGet(request, response);

    }

}


Model.BUtente.validate(mail,pw) returns true if the user (with e-mail=mail and password=pw) is a record of my DB, else returns false, I've tested it and works fine.

                    How to change which sound is reproduced for terminal bell?

                    Image
                    3 Recently upgrade to 18.10 from 18.04, and using the terminal is becoming annoying: the new alert sound is a drip ( /usr/share/sounds/gnome/default/alerts/drip.ogg ), and the previous one is still located at ( /usr/share/sounds/ubuntu/stereo/bell.ogg ). My issue is that at the gnome-terminal, when autocompleting or pressing left BOTH sounds are reproduced, at the same time. I want to just have ubuntu/stereo/bell.ogg active, not both . At the moment I have been only able to reduce the volume of the alerts (but still both are played), or turn the alerts down (but I dislike both "solutions"). gnome-terminal 18.10 teminal-bell share | improve this question

                    Title Spacing in Bjornstrup Chapter, Removing Chapter Number From Contents

                    Image
                    up vote 5 down vote favorite 2 I would like to make it so that the vertical space below the title of each chapter is the same when using the Bjornstrup package (i.e. so that the descenders do not affect the spacing - as shown by the red arrow in the picture below). I think I'm fairly happy with the spacing around "A chapter", so I'd really like titles without descenders (e.g. "Contents") to have the same vertical spacing as "A chapter" below the title. I would also like to remove the large "0" in the contents title. Any help appreciated, as always. documentclass[11pt,a4paper]{book} % Packages[![enter image description here][1]][1] usepackage[left=3.5cm, right=3.5cm, top=4.3cm, bottom=4.25cm]{geometry} usepackage[utf8]{inputenc} usepackage{libertine} usepackage[libertine]{newtx
