In this tutorial, we will show you how to run .jnlp files in a system running Ubuntu/Linux Mint. The extension jnlp (Java Network Launching Protocol) is used to launch and manage Java programs via the internet or network. If you have downloaded a *.jnlp file on your computer and don't know how to execute it, you can simply use javaws to run it.

Getting Started

To install javaws under Ubuntu 12.10/12.04 and Linux Mint 14/13 or older, open the terminal and run these commands:

sudo apt-get install icedtea-netx

Via the terminal, cd to the folder containing your plnp file and run this command:

javaws filename.jlnp

Example:

MSGViewer is an application that allows users to preview Microsoft Outlook MSG files in a Linux-based system. This application is packaged in PLNP file. To run it, you can use the following commands from the terminal:

cd /tmp 
wget http://goo.gl/cTJwB -O launch.jnlp 
javaws launch.jnlp
