Trail: JavaBeans

## Lesson: New JavaBeans Features

> Here is a list of upcoming Beans and Beans-related features:

> - The Java Activation Framework (JAF). The JAF is a data typing and command registry API. With the JAF you can discover an arbitrary data object's type, and look command applications or Beans that can process that data type, and activate the appropriate command at a user gesture. For example, a browser can identify a file's data type, and then launch the appropriate plug-in to view or edit the file. The JAF is a Java standard extension. You can get a copy from the JavaBeans Glasgow web site.

> - The Runtime Containment and Services Protocol, also known as `beancontext`. Previous to this protocol a Bean only knew about and had access to the Java Virtual Machine (JVM) in which the Bean ran, and the core Java APIs. This protocol introduces a standard way for a Bean to discover and access attributes or services provided by a Bean's enclosing environment, and for a Bean's enclosing environment to discover and access a Bean's attributes and services. The `java.beans.beancontext` API introduces the ability to nest Beans and Bean contexts within a hierarchical structure. At runtime, a Bean can obtain services from its containing enviroment; the Bean can then make use of those services, or propagate those services to any Beans that it contains.

> - Drag and Drop Support. The `java.awt.dnd` API provides support for drag and drop between Java applications and native platform applications.
