With the Java Accessibility API, developers can easily create
Java applications that are accessible to persons with disabilities. Accessible Java
applications are compatible with assistive technologies such
as screen readers, speech recognition systems, and refreshable braille
The Java Accessibility API (JAAPI) is one of the core parts of the Java Foundation
Classes (JFC). The JFC are a comprehensive set of graphical user interface
components and foundation services designed to simplify deployment of
Internet, intranet and desktop applications. The JAAPI makes GUI component
information available to assistive technologies,
giving users alternative presentation and control of Java applications.
Java Accessibility Utilities
Accessibility Utilities help assistive technologies take advantage of
the Java Accessibility API. The Utilities monitor events related to UI components.
They also help assistive technologies get additional information about a GUI,
such as the current position of the mouse, or the window that currently has
The Utilities are released separately from the JFC, but they can be downloaded
from the JFC Home Page.
Pluggable Look and Feel
The Java Foundation Classes implement a Pluggable Look and Feel
architecture. This architecture allows non-visual manifestations of a
user interface to replace or enhance the visual presentation of an
application. The expression of the user interface is separated from the
underlying structure and data of each individual component. This is
accomplished by separating the user interface of the component from its
model. The model of a component is the structure which encapsulates the
state and information that is presented to the user by the user interface.

Java Access Bridge for Microsoft Windows The Java Access Bridge for Microsoft Windows allows Windows-native assistive technologies to provide access to Java applications running on Windows
to assistive technologies on Windows.
