+# 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](https://javaee.github.io/javamail)
+and [JAX-WS](https://github.com/javaee/jax-ws-spec) for data content handling.
+
+JAF is included in Java SE 6 and later.
