Registration and Login Form in JSP

In this article, we will see how to develop the Registration and Login Form in JSP. To develop a registration form we will need to connect our JSP application with the database. Here we are using the MySQL database. First, we will create a database name students. The SQL statement will be: Create database students;

Now, create the users table inside the students database as follows:

CREATE TABLE users (
    fname varchar(45),
    lname varchar(45),
    email varchar(100),
    userid varchar(45),
    password varchar(45)
);

In this example, we will create four pages:

  1. Index.html
  2. Login.jsp
  3. Register.html
  4. registrationProcess.jsp

In the index.html page, we are giving two fields where the user will enter his/her “username” and “password” in case the user is already registered. If the user not registered, the user needs to click on the “Login Here” link available. After that user will be redirected to the register.html page where the user has to enter his/her credentials which will redirect to registrationProcess.jsp. This JSP page will save the entered record into the “users” table in the “students” database. After successful registration user can click on the “Login” link which will redirect the user to the index.html page. Where the user can enter the credentials, which will redirect the user to login.jsp page.

Statement st = con.createStatement();
ResultSet rs = st.executeQuery("select * from users where userid='" + userid + "' and password='" + password + "'");
try {
 rs.next();
 if (rs.getString("password").equals(password) && rs.getString("userid").equals(userid)) {
  out.println("<h2>Welcome " + fname "</h2>");
 } else {
  out.println("Invalid password or username.");
 }
} catch (Exception e) {
 e.printStackTrace();

 Statement st = conn.createStatement();
 int i = st.executeUpdate("insert into users(fname,lname,email,userid,password)values('" + fname + "','" + lname
 + "','" + email + "','" + userid + "','" + password + "')");
 out.println("Thank you for register ! Please <a href='index.html'>Login</a> to continue.");
} catch (Exception e) {
 System.out.print(e);
 e.printStackTrace();
}
