How To Make A Login Page In Jsp

Web Development Software

Creating a login page in JSP is an essential step in building any web application that requires user authentication. In this article, I will guide you through the process of creating a login page using JSP, along with some personal insights and commentary.

Getting Started

The first step in creating a login page is to set up the necessary files and directory structure. Create a new folder for your project and inside it, create a new JSP file named login.jsp. This will be our login page where users can enter their credentials and log in to the application.

Next, we need to create a CSS file to style our login page. Create a new CSS file named style.css and link it to your login.jsp file using the <link> tag. You can add your personal touch to the design by customizing the CSS styles according to your preference.

Designing the Login Form

Now, let’s design the login form. Inside the login.jsp file, add the following HTML code:

<form action="login.jsp" method="post">
<label for="username">Username:</label>
<input type="text" id="username" name="username" required>

<label for="password">Password:</label>
<input type="password" id="password" name="password" required>

<button type="submit">Login</button>

In the above code, we have created a simple login form with two input fields for username and password. The form has an action attribute set to “login.jsp” to handle the form submission.

Implementing the Login Functionality

Now, let’s implement the login functionality in our JSP file. Inside the login.jsp file, add the following Java code:

String username = request.getParameter("username");
String password = request.getParameter("password");

// Add your login validation logic here
// Example: check if username and password match a database record

if(username.equals("admin") && password.equals("password")) {
session.setAttribute("loggedIn", true);
} else {
out.println("Invalid username or password!");

This code retrieves the values entered by the user in the login form using the request.getParameter() method. You can add your login validation logic here, such as checking if the username and password match a database record.

If the username and password match, we set a session attribute named “loggedIn” to true and redirect the user to the dashboard page. Otherwise, we display an error message using the out.println() method.


In this article, we have learned how to create a login page in JSP from scratch. We covered the steps to set up the necessary files and directory structure, design the login form using HTML and CSS, and implement the login functionality using Java code.

Remember, the code provided here is just a starting point, and you should customize it based on your specific requirements and security considerations. Building a secure login page is crucial for protecting user data and ensuring the integrity of your web application.

Now, go ahead and create your own login page in JSP, add your personal touch to the design, and start building amazing web applications!
