Running Jetty

Changing the Jetty Port
Starting HTTPS
Stopping Jetty

To start Jetty on the default port of 8080, run the following command:

> java -jar start.jar

You should see about twenty lines of logged INFO statements similar to the following, informing you of the components being started:

You also see some warnings like:

2012-10-22 16:02:24.748:WARN::main: test-realm is deployed. DO NOT USE IN PRODUCTION! 
2012-10-22 16:02:25.582:WARN::main: async-rest webapp is deployed. DO NOT USE IN PRODUCTION!

These warnings are telling you that some demonstration web applications and services are deployed and that you should remove them before putting the server into production. You can ignore these warnings while testing, or you can see Deploying Web Applications to learn how to remove them.

After starting Jetty, you can test it by pointing a browser or any HTTP client at port 8080 of the machine. If you are running the browser on the same machine as the Jetty instance, the URL to use is: http://localhost:8080/ and your browser or HTTP client should see the Jetty welcome page and be able to follow the links to some test web applications.

Changing the Jetty Port

If you see the following exception, you already have something running on the port that Jetty is configured to run on and you either need to shut down whatever that process is, or configure Jetty to run on another port. Address already in use 
  at Method) 

You can configure Jetty to run on a different port by setting the jetty.port Property on the command line:

> java -jar start.jar jetty.port=8081

As alternatives, you can set this property in the start.ini file or by editing the use of the property in the etc/jetty-http.xml configuration file. The way this works is that it defines a property that is the etc/jetty-http.xml configuration file uses to inject a port value into the ServerConnector defined there. For more information see the Quickstart Configuration Guide and Configuring Connectors.

Starting HTTPS

By values set in the start.ini file, Jetty starts the HTTP connector that is defined in etc/jetty-http.xml. To also start the HTTPS connector defined in etc/jetty-https.xml you can simply append this configuration file to the command line:

> java -jar start.jar etc/jetty-https.xml

You can now test this connector by pointing your browser to:


Alternately, you can edit the start.ini file and uncomment the line that includes the HTTPS configuration file and then start Jetty without any extra command line arguments. Note that you can also change the SSL port with the jetty.tls.port Property:

> java -jar start.jar jetty.tls.port=8444 etc/jetty-https.xml

The job of the start.jar command is to interpret the command line and start.ini arguments in order to build a java classpath and list of properties and configuration files to pass to the main class of the Jetty XML configuration mechanism. The start.jar mechanism has many options which are documented in Chapter 16, Starting Jetty; you can see them in summary by using the command:

> java -jar start.jar --help

Stopping Jetty

If you have started Jetty from the command line, it is safe to stop it using the normal Ctrl-C key sequence to abort it. This triggers an orderly shutdown of the server.

However, you might have started the server with some advanced start.jar options so that it runs in the background:

> java -jar start.jar -DSTOP.PORT=8881 -DSTOP.KEY=magic --daemon &

You should shut down this server with the command:

> java -jar start.jar -DSTOP.PORT=8881 -DSTOP.KEY=magic --stop
