Overview

Eclipse Jetty is a Java web server and Servlet container supporting HTTP/1, HTTP/2, HTTP/3, WebSocket, and Servlet workloads. It can run as a standalone distribution for WAR deployment or be embedded directly inside an application. The latest release checked on September 17, 2026 is 12.1.13.

Features and best fit

Based on official documentation; not hands-on tested · Content checked:

Choose between a standalone web server and an embedded library from the same codebase

Jetty is an asynchronous Java web server and Servlet container covering HTTP/1, HTTP/2, HTTP/3, WebSocket, and Servlet workloads. It supports both traditional WAR deployment from a distribution and embedded applications built directly around Server and handlers.

Compose EE8 through EE11 deployments alongside HTTP client/server modules

The 12.1 line includes jetty-core plus EE8, EE9, EE10, and EE11 module families, and the README shows multiple EE deployment generations enabled in the same base. The build targets Java 17, while the project also contains HTTP client, FCGI, WebSocket, and related modules.

For teams that want Servlet/Jakarta EE hosting and embedded HTTP servers in one Java stack

Jetty works for conventional WAR deployments as well as microservices and tools that embed a server inside the application. If you need HTTP protocol handling plus Servlet/container semantics, it is more direct than a lower-level networking framework such as Netty.

Pin the Java and EE generation first, then test module and compliance changes on upgrade

The 12.1 line targets Java 17, and the selected EE8–EE11 modules determine deployment compatibility. Jetty 12.1.13 also changes connection-failure handling, multipart compliance, authentication behavior, and HTTP/3 dependencies. Review module configuration and integration tests when upgrading. Jetty artifacts are offered under EPL-2.0 or Apache-2.0.
