Java Access Bridge Supported Java SE Platforms
Java Access Bridge is included with JRE 7u6 and later.
Enabling Java Access Bridge Through the Command Line
Enable Java Access Bridge with the jabswitch
command.
Run the following command (where %JRE_HOME%
is the directory of your JRE):
%JRE_HOME%\bin\jabswitch -enable
Enabling Java Access Bridge Through the Control Panel
Enable Java Access Bridge through the Control Panel with the Ease of Access Center.
- Click Start, select Control Panel, then Ease of Access, then Ease of Access Center. Alternatively, press Windows logo key + U to access the Ease of Access Center.
- Select Use the computer without a display.
- In the section Other programs installed, select the check box Enable Java Access Bridge (you may have to scroll down).
Disabling Java Access Bridge
Disable Java Access Bridge with the jabswitch
command.
Run the following command:
%JRE_HOME%\bin\jabswitch -disable
Note:
You cannot disable Java Access Bridge through the Windows Ease of Access Center.Testing Java Access Bridge
Test Java Access Bridge by first installing a supported assistive technology then running a Java application that uses the Accessibility API.
Java Access Bridge Tools
Use the jaccessinspector
and jaccesswalker
tools, which are part of the JRE and JDK, to test Java Access Bridge.
jaccessinspector
tool uses the Java Accessibility Utilities API to examine accessible information about the objects in the Java Virtual Machine. The jaccesswalker
tool walks through the component trees in a particular Java Virtual Machine and presents the accessibility hierarchy in a tree view. Find these tools in the JRE's or JDK's bin
directory.
Minimum Version Requirements of Assistive Technologies on 64-Bit Operating Systems
