Java Accessibility Guide > Enabling and Testing Java Access Bridge
Java Access Bridge is a technology that enables Java applications and applets that implement the Java Accessibility API to be visible to assistive technologies on Microsoft Windows systems. See Java SE Desktop Accessibility for more information.
The following topics are covered:
Java Access Bridge is included with Java SE Runtime Environment (JRE) Release 7 Update 6 (7u6) and later. Java Access Bridge 2.0.3 is included with JRE 7u6. By default, Java Access Bridge is not enabled.
To enable Java Access Bridge, run the following command (where
%JRE_HOME% is the directory of your JRE):
Alternatively, in Windows Vista and later, you can enable Java Access Bridge through the Control Panel:
Note: After enabling Java Access Bridge, you must restart your assistive technology software and Java applications that use the accessibility API.
To disable Java Access Bridge, run the following command:
Note: You cannot disable Java Access Bridge through the Windows Ease of Access Center.
To test Java Access Bridge, follow these steps:
The Java Access Bridge testing tools Java Monkey and Java Ferret are not shipped with the JDK. These tools are included in Java Access Bridge 2.0.2. Download this version from Java Access Bridge Downloads.
The following lists the minimum version requirements of some assistive technologies:
Note: It is recommend that you install both the 32-bit and 64-bit versions of the JRE. The 32-bit version only adds support for 32-bit assistive technology, and the 64-bit version only adds support for 64-bit assistive technology.
The JDK contains a private JRE. This is required to run tools included with the JDK. If you do not install the public JRE either as an option when installing the JDK or by installing the JRE by itself, and you intend to use the private JRE of the JDK, you will need to manually copy files as specified in the following table:
|JDK||Windows Operating System||File to Copy||Destination Directory|
