What Is a Tomcat Web Server?


Larry Thompson

A Tomcat web server is a popular open-source implementation of the Java Servlet, JavaServer Pages (JSP), and WebSocket technologies. It is developed and maintained by the Apache Software Foundation and is designed to be highly scalable, reliable, and efficient for hosting Java-based web applications.

What is a Web Server?

Before we dive into the specifics of a Tomcat web server, let’s first understand what a web server is. In simple terms, a web server is software that runs on a computer and enables it to serve web pages to clients over the internet. When you type a website URL into your browser’s address bar, it sends a request to the web server associated with that URL, which then responds by sending back the requested web page.

Key Features of Tomcat

1. Servlet Container: Tomcat acts as a servlet container that provides an environment for deploying and running Java servlets. Servlets are Java classes that dynamically generate HTML content or process user input within a web application.

2. JSP Support: Tomcat supports JavaServer Pages (JSP), which allow developers to embed Java code within HTML pages. JSP pages are compiled into servlets by Tomcat at runtime.

3. WebSockets: Tomcat also supports WebSocket technology, which enables full-duplex communication between clients and servers over a single TCP connection.

Advantages of Using Tomcat

Simplicity: One of the primary advantages of using Tomcat is its simplicity in configuration and deployment. It provides an easy-to-use administration interface that allows you to manage your applications efficiently.

Lightweight: Tomcat has a small footprint compared to other Java application servers, making it suitable for resource-constrained environments. It starts up quickly and consumes fewer system resources.

Compatibility: Tomcat is built to be compatible with the latest Java EE specifications, ensuring that your web applications can take advantage of the latest features and enhancements provided by the Java platform.

Setting Up Tomcat

Setting up Tomcat is relatively straightforward. Here are the steps to get started:

  • Step 1: Download the latest version of Tomcat from the official Apache Tomcat website.
  • Step 2: Extract the downloaded archive to a directory on your computer.
  • Step 3: Configure any necessary environment variables, such as JAVA_HOME, to point to your Java installation.
  • Step 4: Start Tomcat by executing the startup script located in the bin directory of your Tomcat installation.

The Bottom Line

In conclusion, a Tomcat web server is a powerful and versatile tool for hosting Java-based web applications. Its ease of use, lightweight nature, and compatibility with industry standards make it a popular choice among developers. Whether you are a beginner or an experienced developer, incorporating Tomcat into your development stack can help you streamline your web application deployment process.
