Is Tomcat a Web Server?

When it comes to web development, understanding the different components that make up a web application is crucial. One common question that often arises is whether Tomcat is a web server or something else entirely. In this article, we will delve into the details and clarify the role of Tomcat in the web development landscape.

The Basics: What is a Web Server?

Before we jump into discussing Tomcat, let’s first establish what exactly a web server is. In simple terms, a web server is software that runs on a computer and serves web pages to clients upon receiving HTTP requests. It listens for incoming requests, processes them, and sends back the requested resources.

Common examples of web servers include Apache HTTP Server, Nginx, and Microsoft IIS. These servers are responsible for handling client requests and returning HTML documents, images, CSS files, and more.

Introducing Tomcat

Now that we have an understanding of what a web server does let’s talk about Tomcat. Apache Tomcat, often referred to as just “Tomcat,” is an open-source Java Servlet Container developed by the Apache Software Foundation.

Tomcat primarily functions as a Java-based web application server. It provides an environment for running Java-based applications on a server.

However, it’s important to note that Tomcat can also be used as a standalone web server. This means that it can handle incoming HTTP requests and serve static files like HTML documents and images without relying on another external web server.

Tomcat vs. Other Web Servers


  • Primarily serves as a Java-based web application server
  • Can also function as a standalone web server
  • Supports Java Servlet, JavaServer Pages (JSP), and other Java-based technologies
  • Provides an environment for running Java-based applications


  • Serves as a traditional web server
  • Handles static files like HTML, CSS, images, etc.
  • Supports various programming languages and technologies through modules
  • Often used in combination with Tomcat to handle different aspects of web development

The Power of Tomcat: A Closer Look at its Features

Tomcat’s versatility is one of its standout features. Let’s explore some of the key capabilities that make it an excellent choice for Java-based web development:

JSP and Servlet Support

Tomcat provides full support for JavaServer Pages (JSP) and Java Servlet technologies. This means that you can develop dynamic web pages using JSPs and handle HTTP requests with Servlets seamlessly. Tomcat takes care of the underlying infrastructure required to run these technologies efficiently.

JNDI Support

The Java Naming and Directory Interface (JNDI) allows applications to access naming and directory services in a standardized way. Tomcat provides built-in support for JNDI, making it easier to connect to databases, messaging systems, or other enterprise resources. This feature enables developers to build robust and scalable applications with ease.

Ease of Deployment

Tomcat simplifies the deployment process by providing easy-to-use tools and a well-defined directory structure. You can package your web application as a WAR (Web Application Archive) file and deploy it to Tomcat effortlessly. This streamlined deployment process saves time and effort, allowing developers to focus on building the application itself.


In conclusion, Tomcat is indeed a web server, but its primary role lies in serving Java-based web applications. Its ability to function as both a Java Servlet Container and a standalone web server makes it a powerful tool for developers. With its support for JSP, Servlets, JNDI, and easy deployment capabilities, Tomcat offers an excellent platform for developing robust and scalable Java web applications.

So the next time you come across the question “Is Tomcat a web server?”, you can confidently answer yes, while also keeping in mind its broader functionality in the world of Java-based web development.
