Project description

Jetty is a lightweight highly scalable java based web server and servlet engine. Our goal is to support web protocols like HTTP, HTTP/2 and WebSocket 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 async web server that has a long history as a component oriented technology 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 3.8.0 and OpenJDK requirements:

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

Full Build with All Tests:

mvn clean install

Fast Build if you need jars and distribution (not running tests, checkstyle, enforcer, license check):

mvn -Pfast clean install

Optional build tools:

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

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:

Branches	Location	Description
all	jetty-home/target/jetty-home-<ver>.tar.gz	The Jetty Home standalone tarball
jetty-10.0.x	jetty-runner/target/jetty-runner-<ver>.jar	The Jetty Runner uber jar
jetty-11.0.x	jetty-runner/target/jetty-runner-<ver>.jar	The Jetty Runner uber jar
jetty-12.0.x	jetty-ee10/jetty-ee10-runner/target/jetty-ee10-runner-<ver>.jar	The Jetty Runner uber jar for ee10/Servlet 6 (jakarta.servlet) webapps
jetty-12.0.x	jetty-ee9/jetty-ee9-runner/target/jetty-ee9-runner-<ver>.jar	The Jetty Runner uber jar for ee9/Servlet 5 (jakarta.servlet) webapps
jetty-12.0.x	jetty-ee8/jetty-ee8-runner/target/jetty-ee8-runner-<ver>.jar	The Jetty Runner uber jar for ee8/Servlet 4 (javax.servlet) webapps

Note: The build tests do a lot of stress testing, and on some machines it is necessary to set the file descriptor limit to greater than 2048 for the tests to all pass successfully (check your ulimit -n value).
