In this application I create a Jetty server and want to combine it with Jersey ( JAX-RS). That works fine. That works fine. But now I want to add a ResourceHandler to server static JS, CSS and images from the webapp/ directory. Jetty 9.3.6 and Oracle Java 8 installed, JAVAHOME pointing to the Java 8 installation, Jetty placed in /opt/jetty. Login as root or use all commands in sudo context. Let's begin in the /opt/jetty/lib folder: cd /opt/jetty/lib. Create an obfuscated password. The core jetty server artifact.

Throughout this tutorial we have been using Jetty on a local computer.In this chapter we show how to install Jetty on a remote server. This gives us a more realistic experience in managing a Jetty server.
We use a debian-based Linux system.
First, we update the server.
Next, we install Java if it is not already present on the system.We use the OpenJDK implementation. The openjdk-7-jre-headless is a minimal Java runtime—the components for executing Java GUIprograms are not needed on servers and are not included in this package.
We download and unpack a Jetty distribution inside the /tmp directory.
Jetty is moved to /opt/jetty directory. The archive is removed.
The demo applications that come with Jetty distribution are removed.
The /etc/environment file is used for system-wide environment variable settings. We set JAVA_HOME, JETTY_HOME, and JETTY_BASE environment variables there.
The source command evaluates the file and sets the variables. We cannow start referring to the new variables.
A new jetty user and group are added to the system. Jetty will run under this useron the system. Setting the user's shell to /bin/false has the affect of not allowing someone to log in under this username.
New directories are created. The /opt/web/mybase will hold the Jetty base, the /opt/jetty/temp will be used for temporary files of Jetty.According to the Jetty documentation, it is a best practice to create a separatetemporary directory from the standart system /tmp. Cleanup scripts may interfere with the Jetty's temporary files.
We change the user and group ownership for files and directories relevant for Jetty.The -R option operates recursively on files and directories, which means that the ownership is changed for all directories and files under parent directories.

We add our user name to the jetty group in order to be able to have permissions to operate Jetty.
Next, we enable Jetty as a system service. The servicesare kept in the init.d directory.
The script loads the contents of the /etc/default/jetty file.Inside the file, we set three environment variables.
Jetty is started as a system service.
With the status parameter, we can check a service'sstatus.

From the development computer, we deploy a simple web application by copying a project WAR file to the webapps directory of the Jetty base.
We connect to the web application and receive HTML output.
Here we use a packet filter to forward all incoming packets to port 80 to port 8080.The default port on which Jetty listens is 8080; it is configured in thestart.ini file. The chicken jaco birthday.
Now we can refer to the webpage without the port number.
In this chapter, we have installed Jetty on a remote Linux server, enabledit as a system service, and deployed a simple web application.
