How To Create Login Page In Jsp Using Eclipse

How To Articles

Creating a login page is a crucial step in building a secure web application. In this article, I will guide you through the process of creating a login page in JSP (JavaServer Pages) using Eclipse, one of the most popular integrated development environments (IDEs) for Java development. I’ll share my personal insights and provide detailed instructions to help you get started.

Setting up Eclipse

Before we dive into creating the login page, make sure you have Eclipse installed on your system. If you don’t have it yet, you can download it from the official Eclipse website and follow the installation instructions for your operating system.

Creating a New Dynamic Web Project

Once you have Eclipse up and running, let’s create a new Dynamic Web Project. Follow these steps:

  1. Open Eclipse and select File > New > Dynamic Web Project.
  2. Enter a name for your project and choose a target runtime (e.g., Apache Tomcat).
  3. Click Next and make sure the Generate web.xml deployment descriptor option is checked. This will create the necessary configuration file for our web application.
  4. Click Finish to create the project.

Creating JSP Files

Now that we have our project set up, let’s create the JSP files for our login page. Follow these steps:

  1. Right-click on the project in the Package Explorer view and select New > File.
  2. Enter a name for the JSP file (e.g., login.jsp) and click Finish.
  3. In the newly created JSP file, add the HTML markup for your login page. You can customize the design and layout of the page according to your preferences.
  4. Add a <form> element to the HTML markup and specify the action URL for the form submission. This URL will point to a servlet that will handle the login functionality.
  5. Inside the <form> element, add <input> elements for the username and password fields, as well as a submit button.

Creating a Servlet

In order to handle the login functionality, we need to create a servlet. Follow these steps:

  1. Right-click on the project in the Package Explorer view and select New > Servlet.
  2. Enter a name for the servlet (e.g., LoginServlet) and click Next.
  3. Specify the URL mapping for the servlet (e.g., /login) and click Next.
  4. Choose the doPost() method and click Finish.
  5. In the doPost() method, retrieve the values of the username and password parameters from the request object, and perform the necessary validation and authentication logic.
  6. Based on the result of the authentication, redirect the user to the appropriate page.

Testing the Login Page

Now that we have our login page and servlet in place, it’s time to test our implementation. Follow these steps:

  1. Start the Apache Tomcat server from within Eclipse.
  2. Open a web browser and navigate to the following URL:
