JAR (Java ARchive )
(Free Web Tutorials)

by Michael Thomas

JAR (Java ARchive) is a zip type file that contains files (normally classes and other files) and an optional META-INF directory containing package and extension configuration data, including security, versioning, extension and services .  This allows the deployment of one file that contains a collection of files.  Java applications and Applets can use JAR files.
(Note: With a Zip program you can open, extract and actually create a JAR but you should create the file with the "jar" command.)
