Mastering the Basics: Building a Java Web Application from Scratch

Introduction:

In today’s digital era, web applications have become an integral part of our lives. From social media platforms to e-commerce websites, Java plays a significant role in powering the backend of these applications. In this article, we will embark on a journey to create a basic web application using Java. By the end of this tutorial, you will have a solid foundation to build upon and explore the vast possibilities of web development with Java.

Setting Up the Environment:

Before diving into coding, let’s set up our development environment. We will require the following tools:

1. JDK (Java Development Kit): Ensure that you have the latest version of JDK installed on your machine.
2. Integrated Development Environment (IDE): Choose an IDE that suits your preferences, such as Eclipse, IntelliJ IDEA, or NetBeans.
3. Servlet Container: We will use Apache Tomcat as our servlet container. Download and configure it according to your system requirements.

Creating the Project Structure:

1. Open your IDE and create a new Java project. Give it a suitable name and set the project location.
2. Inside the project, create a new package called “com.example.webapp” (replace “example” with your preferred name). This package will hold all our classes related to the web application.
