JNLP, or Java Network Launch Protocol, makes it possible to run a Java application on your computer using files and resources stored on a remote web server. Tools like Java Web Start and the Java Plug-in act as JNLP clients because they let you open and run these remote Java programs directly on your desktop.
The usual method for accessing a server’s iLO or IPMI console is by downloading and launching a JNLP file from the server’s web interface. Since I’m using a Linux desktop, I needed to find a tool that could open and run this file properly. In this guide, we will install IcedTea-Web which is a free software implementation of Java Web Start and the Java web browser plugin.
