Opening JNLP files

Did your computer fail to open a JNLP file? We explain what JNLP files are and recommend software that we know can open or convert your JNLP files.

What is a JNLP file?

JNLP is an acronym for Java Network Launching Protocol. The JNLP file format is used by Java to launch and manage various Java applications over a network or on the Internet. The JNLP files are saved in the XML file format. The files are actually comprised of a group of protocols that define the specific requirements of a JAVA launching mechanism.

Unlike typical web applets, JNLP files are not run within a user's Web browser. These files are actually downloaded onto a user's computer and are then run as normal Java applications. The files are used only for stand-alone applications.
