Created my first webapplication using Servlet and a tomcat server. Basic concept is people can register themselves to be members of a fanclub and can then see who the people are that registered.

When I deploy the tomcat server I get to my indexpage just fine, same for my member register webpage. But then when I click the submit button it should redirect to my Servlet and add the given credentials to it's database and print them out.

This is where I get my error 404 with description: Description The origin server did not find a current representation for the target resource or is not willing to disclose that one exists.

I believe the problem has something to do with the way my webpages are linked. Although I'm honestly not really sure at this point.

Help is greatly appreciated.

@WebServlet("/opdracht_get_post_website_war_exploded/Servlet")
public class Servlet extends HttpServlet {
    private RegistratieDB dataBank = new RegistratieDB();
    protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {

                String naam = request.getParameter("Voornaam");
                String achternaam = request.getParameter("achternaam");
                String loginnaam = request.getParameter("loginnaam");
                String passwoord = request.getParameter("passwoord");
                String email = request.getParameter("email");
                String niveau = request.getParameter("niveau");

                Registratie voegToe = new Registratie(naam, achternaam, loginnaam, passwoord, email, niveau);
                dataBank.add(voegToe);

            RequestDispatcher view = request.getRequestDispatcher("leden.jsp");
            view.forward(request, response);
    }

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

        RequestDispatcher view = request.getRequestDispatcher("leden.jsp");
        view.forward(request, response);
    }
}

  • What do access logs say? Can you print them in your quesion ? – Dawid D Mar 10 '20 at 19:47
  • Where can I find those? – pieterjan Mar 10 '20 at 19:49
  • /logs. The main log file is the catalina.out file where you can find error messages. – Dawid D Mar 10 '20 at 19:52
  • Could you remove in this line https://github.com/pieterjan-dubois/opdracht_get_post_website/blob/master/web/registratie.jsp#L32 the first "/" and try again. – JuanMoreno Mar 10 '20 at 19:57
  • Will do @SHoko and Dawid D I restarted tomcat server and navigated until I got the problem and copied those logs. – pieterjan Mar 10 '20 at 19:59
  • When removing the first / like you said gives me this: https://imgur.com/2tbBL8w – pieterjan Mar 10 '20 at 20:02
  • Ok, I understand that you `action` entry will be "opdracht_get_post_website_war_exploded/Servlet" – JuanMoreno Mar 10 '20 at 20:02
  • when including the first / I get localhost:8080/opdracht_get_pos_website_exploded/Servlet with the / removed it's localhost:8080/opdracht_get_pos_website_exploded/opdracht_get_pos_website_exploded/Servlet – pieterjan Mar 10 '20 at 20:05
  • Could you update this line too https://github.com/pieterjan-dubois/opdracht_get_post_website/blob/c141cd0ab4173f1f3f84b45e5f9d7b80644ead4a/src/ui/controller/Servlet.java#L15? Would be `@WebServlet("/Servlet")` – JuanMoreno Mar 10 '20 at 20:05
  • With first / removed and @webServlet("/Servlet") I get this pressing the register button: https://imgur.com/tdcVqoc – pieterjan Mar 10 '20 at 20:10
  • When I do action="Servlet" instead of opdracht_get_post_website_war_exploded/Servlet in the registratie.jsp file I get this error might help you more: https://imgur.com/9UvkVgh – pieterjan Mar 10 '20 at 20:16
  • I figured it out :) thanks for helping me in the right direction, I can finally sleep @SHoko – pieterjan Mar 10 '20 at 20:34
