JavaBeans Activation Framework (JAF)

The JavaBeans Activation Framework (JAF) is a standard extension to the Java platform that lets you take advantage of standard services to: determine the type of an arbitrary piece of data; encapsulate access to it; discover the operations available on it; and instantiate the appropriate bean to perform the operation(s).

JAF is used by JavaMail and JAX-WS for data content handling.

JAF is included in Java SE 6 and later.

This standalone release of JAF uses a Java Platform Module System "automatic" module name of java.activation, to match the module name used in JDK 9. A future version will include full module metadata.
