The Java Network Launching Protocol (JNLP) is the file format used by Java Web Start, a Java component that allows programs to be run outside of the browser (i.e. not as applets) but still in a sandbox. Users download the JNLP file and give it to an interpreter, which in turn downloads resources (Jar files, splash screens, etc.) whose URLs are listed by the file, and runs them. JNLP is based on XML. Java Web Start, like the applet system, eventually fell into disuse, and it was finally removed in Java version 11[3] in 2018[4].
