My java servlet is not working at maven (netbeans)

Question

I have a web project with maven at netbeans. I'm using glassfish & MySQL.

This is my registration screen newUserScreen

After clicking "Tamam", I want to take a registration from web to my database but I am just seeing my servlet url and nothing is happening. emptyUserServletUrlScreen

This is my servlet :

package tr.kasim.cc.servlet;

import java.io.IOException;
import java.io.PrintWriter;
import java.util.ArrayList;
import java.util.logging.Level;
import java.util.logging.Logger;
import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import tr.kasim.cc.app.Application;
import tr.kasim.cc.util.GeneralUtil;
import tr.kasim.cc.model.SignUp;

@WebServlet(urlPatterns = {"/userservlet"})
public class SignUpUsersServlet  extends HttpServlet {

    @Override
    protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
        doProcess(req, resp);
    }

    @Override
    protected void doPost(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
        doProcess(req, resp);
    }

    protected void doProcess(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
        PrintWriter out = null;
        try {
            out = new PrintWriter(resp.getOutputStream());

            String action = req.getParameter("action");
            if ("addUser".equals(action)) {
                addUser(req, resp);
            }

        } catch (Exception ex) {
            Logger.getLogger(SignUpUsersServlet.class.getName()).log(Level.SEVERE, null, ex);
            System.out.println("hata var agacim");
        } finally {
            if (out != null) {
                out.flush();
                out.close();
            }
        }
    }

    public void addUser(HttpServletRequest req, HttpServletResponse resp) throws Exception, IOException {

        String loginName = req.getParameter("loginName");
        String password = req.getParameter("password");
        String eMail = req.getParameter("eMail");
        String userName = req.getParameter("userName");
        String userDate = req.getParameter("userDate");
        String userJob = req.getParameter("userJob");
        String userTelephone = req.getParameter("userTelephone");
        String userCity = req.getParameter("userCity");
        String userGenderId = req.getParameter("userGenderId");

        SignUp sign_up = new SignUp(null,loginName,password,eMail,userName,userDate,userJob,userTelephone,userCity,userGenderId);

        Application.getApp().getMainService().addUser(sign_up);
        resp.sendRedirect("./userList.jsp");
    }

}

Now I could not take any registration. What do you think? Where/What is my error?

Answer 1

First your annotation is wrong. Change it to

@WebServlet(name = "SignUpUsersServlet", urlPatterns = {"/userservlet"})

and it should work fine.

Second you need to include requestDispatcher in your servlet code.

Change

resp.sendRedirect("./userList.jsp");

to

RequestDispatcher rd = request.getRequestDispatcher("userList.jsp");
rd.forward(request, response);

Third get rid of your doProcess and addUser methods and work only with doGet and doPost.

And if you want to have doProcess and addUser where are you calling addUser in doGet or doPost you are only call doProcess there.
