Eclipse Jetty

Eclipse Jetty is a lightweight, highly scalable, Java-based web server and Servlet engine. Jetty's goal is to support web protocols (HTTP/1, HTTP/2, HTTP/3, WebSocket, etc.) in a high volume low latency way that provides maximum performance while retaining the ease of use and compatibility with years of Servlet development. Jetty is a modern fully asynchronous web server that has a long history as a component oriented technology, and can be easily embedded into applications while still offering a solid traditional distribution for webapp deployment.

Webapp Example

$ mkdir jetty-base && cd jetty-base
$ java -jar $JETTY_HOME/start.jar --add-modules=http,ee10-deploy
$ cp ~/src/myproj/target/mywebapp.war webapps
$ java -jar $JETTY_HOME/start.jar

Multiple Versions Webapp Example

$ mkdir jetty-base && cd jetty-base
$ java -jar $JETTY_HOME/start.jar --add-modules=http,ee10-deploy,ee8-deploy
$ cp ~/src/myproj/target/mywebapp10.war webapps
$ cp ~/src/myproj/target/mywebapp8.war webapps
$ echo "environment: ee8" > webapps/mywebapp8.properties
$ java -jar $JETTY_HOME/start.jar

Embedded Jetty Example

Server server = new Server(port);
server.setHandler(new MyHandler());
server.start();

Embedded Servlet Example

Server server = new Server(port);
ServletContextHandler context = new ServletContextHandler("/");
context.addServlet(MyServlet.class, "/*");
server.setHandler(context);
server.start();

Building Jetty from Source

$ git clone https://github.com/jetty/jetty.project.git
$ cd jetty.project
$ mvn -Pfast clean install # fast build bypasses tests and other checks

Documentation

Jetty's documentation is available on the Eclipse Jetty website.

The documentation is divided into three guides, based on use case:

The Operations Guide targets sysops, devops, and developers who want to install Eclipse Jetty as a standalone server to deploy web applications.
The Programming Guide targets developers who want to use the Eclipse Jetty libraries in their applications, and advanced sysops/devops that want to customize the deployment of web applications.
The Contribution Guide targets developers that wish to contribute to the Jetty Project with code patches or documentation improvements.

Commercial Support

Expert advice and production support of Jetty are provided by Webtide.
