Editing JAR (file format) (section)

==Executable JAR files==
An executable Java program can be packaged in a JAR file, along with any libraries the program uses. Executable JAR files have the manifest specifying the [[entry point]] class with <code>Main-Class: myPrograms.MyClass</code> and an explicit Class-Path (and the -cp argument is ignored). Some operating systems can run these directly when clicked. The typical invocation is <code>java -jar foo.jar</code> from a command line.

Native launchers can be created on most platforms. For instance, Microsoft Windows users who prefer having Windows [[EXE]] files can use tools such as JSmooth, Launch4J, WinRun4J or [[Nullsoft Scriptable Install System]] to wrap single JAR files into executables.
