I am trying to create a registration page using the code below however, it doesn't work. It doesn't store the data into the registration table that i created. i need help fixing it. The program uses intellij IDEA html and java.

Registrationservlet.java

package com.example.demo; import java.io.*; import java.sql.Connection; import java.sql.DriverManager; import java.sql.PreparedStatement; import java.sql.SQLException; import javax.servlet.ServletException; import javax.servlet.http.*; import javax.servlet.annotation.*; @WebServlet(name = "registrationServlet", value = "/registration-servlet") public class RegistrationServlet extends HttpServlet { private String message; public void init() { message = "Welcome!"; } public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { response.setContentType("text/html"); PrintWriter out = response.getWriter(); String username = request.getParameter("uname"); String password = request.getParameter("pword"); String email = request.getParameter("email"); String repass = request.getParameter("repass"); try{ Class.forName("oracle.jdbc.driver.OracleDrive"); Connection conn = DriverManager.getConnection( "jdbc:oracle:thin:@localhost:1521:xe","system","oracle"); PreparedStatement ps=conn.prepareStatement( "insert into registeruser values(?,?,?,?)"); ps.setString(1,"name"); ps.setString(2,"pword"); ps.setString(3,"email"); ps.setString(4,"repass"); } catch (ClassNotFoundException | SQLException e) { e.printStackTrace(); } if(username.equals("Amali")) { // Hello out.println("

" + username + "

"); } else { // Hello out.println("

"); } out.println(""); } public void destroy() { } }
