I am a new learner of Java. I have just started to learn Java from last month and still not that well versed with it. Yesterday while reading a book on Java I came accross something named JNLP. There was no definition given for this thing. Only its full form was given which is Java Network Launching Protocol. Please give me some simple and understanding definition for it ?
JNLP is a Java protocol developed by Sun Microsystems. JNLP is an acronym for Java Network Launching Protocol. The JNLP protocol is defined with an XML schema. This defines how to launch Java Web Start applications. It defines a set of rules for implementing the launching mechanism for Java Web Start. Java Network Launch Protocol (JNLP) uses a descriptor file for defining the startup procedure. JNLP consists of information about the name of the main class for the application and location of the jar package file.
The Java Network Launching Protocol i.e JNLP, is a new Java protocol to allow remote applications to be downloaded and run on a client machine. All class files images, etc, can be downloaded which are not present on the client's machine. Any computer user can use JNLP by simply installing a JNLP client, mostly Java Web Start.
The Java Network Launching Protocol (JNLP) is developed through the Java Community Process as JSR-56. A JNLP client is service which be used to launch different applications from resources hosted on a network. By packing the apllication with JNLP the client can easily:
Launch the application from the web browser or the desktop, Run as either an applet or an application, Detect, install, and use the most accurate version of the Java Runtime Environment(JRE) for the application, Download native libraries if necessary, Cache classes used by the application locally for fast startup.
