When it comes to choosing a servlet container for your web applications, the decision often boils down to Jetty and Tomcat. Both are open servlet containers that support HTTP server, HTTP client, and javax.servlet container. In this article, we will delve into a comprehensive comparison of Jetty and Tomcat, aiming to provide an in-depth analysis of their performance, features, and advantages. By the end of this article, you will have a clear understanding of which one might be better suited for your specific needs.

Jetty VS Tomcat Overview

Let’s start by understanding the fundamental differences between Jetty and Tomcat, exploring their popularity, features, and advantages.

Popularity

Tomcat has been the more widely discussed and used servlet container, primarily due to its extensive options for developers. It is known for its user-friendly nature and being freely available. As an eminent free application server, Tomcat offers full web server functionality and can be tailored to be embedded or built up as a complete J2EE server.

Jetty, on the other hand, is a robust tool known for its distinctive features. Established in 1998, Jetty touts itself as a “100% Java HTTP Server and Servlet Container.” It operates as a set of software components providing HTTP and servlet services. Jetty can function as a standalone application server or can be seamlessly integrated into an application or framework as an HTTP component. Whether used as a simple servlet engine, a feature-rich servlet engine, or as part of a full JEE environment, Jetty offers flexibility and versatility.

Their Features and Advantages

Jetty Features and Powered

Jetty is celebrated for its lightweight nature, making it an ideal choice for resource-constrained environments. It boasts a small footprint, high scalability, and exceptional performance, making it suitable for both small-scale and large-scale applications. Furthermore, Jetty supports asynchronous processing, allowing it to handle a large number of concurrent connections efficiently. Its modular architecture enables easy customization and integration with various technologies, ensuring adaptability and extensibility.

Powered by Eclipse Jetty, the servlet container is well-regarded for its WebSocket support, enabling real-time communication between clients and servers. Additionally, Jetty provides comprehensive documentation and a supportive community, facilitating smooth adoption and troubleshooting.

Tomcat Features and Powered

Tomcat, backed by the Apache Software Foundation, is renowned for its stability and maturity. It offers a wide array of configuration options, making it versatile and adaptable to diverse deployment scenarios. With robust support for the latest Java EE specifications, Tomcat ensures compatibility with a broad range of enterprise applications. Moreover, Tomcat benefits from a large and active user community, providing ample resources for assistance and knowledge sharing.

Tomcat’s extensive ecosystem includes numerous third-party modules and extensions, expanding its capabilities and enhancing its utility for different use cases. Its proven track record in handling complex web applications and its seamless integration with various development tools make it a popular choice among developers and enterprises.
