Jetty is a Java-based web server and servlet container developed by Eclipse Foundation. It is designed to be highly scalable, efficient, and customizable, making it suitable for a wide range of web applications, from small to large-scale enterprise systems.
History
Jetty was first released in 1995 by a team led by Greg Wilkins. It was initially designed as a lightweight, high-performance web server for serving static content. Over the years, Jetty has undergone significant development, and in 1999, it was donated to the Apache Software Foundation (ASF). In 2006, the ASF transferred the Jetty project to the Eclipse Foundation, where it remains to this day.
Architecture
Jetty is built on top of a modular architecture, allowing developers to easily add or remove components as needed. The framework consists of several key components:
- Server: The server module is responsible for handling incoming requests and sending responses. It supports various protocols, including HTTP/1.1, HTTP/2, and WebSocket.
- Connector: The connector module manages the communication between the server and clients. It supports various connection protocols, including TCP, UDP, and SSL/TLS.
- Handler: The handler module is responsible for processing incoming requests and generating responses. It can be customized using a variety of handler implementations.
- Servlet Container: The servlet container module provides a runtime environment for deploying and executing servlets.
