What is a JNLP file?

A JNLP file is created in the Java Network Launching Protocol (JNLP) format. It contains information such as the remote address for downloading a Java program (.JAR file) and the initial class to run. JNLP files are used for launching and managing Java programs over a network or on the web.

More Information

JNLP files are saved in an XML format and can be viewed or edited with a text editor. They can be double-clicked to run the program if the Java Runtime Environment (JRE) is installed. The JRE includes Java Web Start technology, which opens JNLP files and runs the specified instructions.

NOTE: Oracle deprecated Java Web Start in the Java Platform Standard Edition (JSE) 9 and removed it altogether in Java SE 11. However, OpenWebStart was developed as an open-source implementation to allow users to still utilize Java Web Start and JNLP applications.
