Open JNLP files on Linux – Ubuntu / Debian / Fedora / Arch

The Java Network Launch Protocol (JNLP) is a protocol which enables an application to be launched on a client desktop by using resources that are hosted on a remote web server. Java Plug-in software and Java Web Start software are considered JNLP clients because they can launch remotely hosted applets and applications on a client desktop.

The standard way of accessing Server iLO/IPMI is via JNLP file downloaded from the server console. I had to find a tool which will allow me to launch this file on my Linux Desktop.

In this guide, we will install IcedTea-Web which is a free software implementation of Java Web Start and the Java web browser plugin.

sudo apt update
sudo apt install default-jdk
