Project description

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 base && cd 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 base && cd 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 Example

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

Building

Apache Maven and OpenJDK requirements:

Branch	Maven Version	Minimum JDK	Recommended JDK
jetty-10.0.x	Maven 3.8.6+	OpenJDK 11	OpenJDK 17 (for optional virtual threads and HTTP/3 support)
jetty-11.0.x	Maven 3.8.6+	OpenJDK 11	OpenJDK 17 (for optional virtual threads and HTTP/3 support)
jetty-12.0.x	Maven 3.8.6+	OpenJDK 17	OpenJDK 17

Full Build

If you want to build Jetty and run all the tests, which may takes quite some time, use the following command:

mvn clean install

Note: There are stress tests that on some hardware or operative system require to set the file descriptor limit to a value greater than 2048 to pass successfully (check your ulimit -n value).

Note: The tests are running in parallel using Junit5 parallel execution. This is configurable using the following properties:

    # to enable/disable the parallel execution
    -Djunit.jupiter.execution.parallel.enabled=true/false
    # number of tests executed in parallel
    -Djunit.jupiter.execution.parallel.config.fixed.parallelism=2

If a test cannot be run in parallel because it accesses/modifies some static fields or for any other reasons, the test should be marked with the annotation:

@Isolated("Access static field of Configurations")

Fast Build

If you just need the Jetty module jars and the Jetty Home distribution, you can run a fast build that does not run tests and other checks with the following command:

mvn -Pfast clean install

Optional Build Tools

• graphviz - used by asciidoctor in the jetty-documentation module to produce various graphs
• Docker - used to run some integration tests for testing third party integrations

Build Artifacts

Once the build is complete, you can find the built Jetty Maven artifacts in your Maven local repository, along with the following locations of note:
