A JAR (Java ARchive) is a zipped file that contains a set of Java CLASSES. It is used to store compiled Java classes and associated metadata that can constitute a program. A JAR acts like a callable program library for Java CODE elements (so that a single compilation LINK provides access to multiple elements, rather than REQUIRING bindings for each element individually).

JAR files can be registered as reusable Oracle Service Bus resources. They are used in Java callout actions that provide a Java exit mechanism, EJB-based business SERVICES, and Tuxedo-based business services.
