This article covers in depth the configuration of Jetty on Javelin as relevant to the CLACI project.
The following changes have been made to the server:
Installation of Jetty
Jetty v9.3.9 is currently installed at /opt/jetty
Jetty is registered as a service in /etc/init.d/, and can be controlled using the following commands:
| Action | Command |
|---|---|
Start the server | sudo service jetty start |
Stop the server | sudo service jetty stop |
Restart the server | sudo service jetty restart |
Directory structure and the Fedora web app
The most important (from our perspective) subdirectories/files within /opt/jetty/ are the following:
| Subdirectory/File | Purpose |
|---|---|
| bin/ | contains jetty.sh, which is the script that is invoked when the service command (described above) is used |
| etc/ | contains XML files that form a superset of all configuration options that Jetty is capable of using |
| demo-base/ | contains demo projects that ship with Jetty |
| fedora/ | this is our custom-created directory, i.e. a "Jetty Base" (also pointed to by environment variable $JETTY_BASE) which contains a full context of files and resources needed to run Fedora as a web app |
| start.jar | this is the JAR file that is eventually parameterized and excecuted when Jetty is started |
Environment Variables
The following environment variables have been applied globally (i.e. in /etc/environment)
| Name of Variable | Value |
|---|---|
$JAVA_HOME | /usr/lib/jvm/java-1.8.0-openjdk-amd64/ |
$JETTY_HOME | /opt/jetty/ |
$JETTY_BASE | /opt/jetty/fedora/ |
