3 Enabling and Testing Java Access Bridge

By default, Java Access Bridge is not enabled. Enable it either through the command line or the Windows Control Panel. Test it by running a Java application that uses the Accessibility API.

Enabling Java Access Bridge Through the Command Line

Enable Java Access Bridge with the jabswitch command.

Run the following command (where %JAVA_HOME% is the directory of your JDK):

%JAVA_HOME%\bin\jabswitch -enable

Disabling Java Access Bridge

Disable Java Access Bridge with the jabswitch command.

Run the following command:

%JAVA_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.

  1. Ensure that Java Access Bridge is enabled.
  2. Install an assistive technology product that supports Java Access Bridge such as one of the following products:
  3. Run a Java application that uses the javax.accessibility package and ensure that your assistive technology product works properly with it.

Java Access Bridge Tools

Use the jaccessinspector and jaccesswalker tools, which are part of the JDK, to test Java Access Bridge.

The 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 JDK's bin directory.

Minimum Version Requirements of Assistive Technologies

This topic lists the minimum version requirements of some assistive technologies.

  • JAWS: Version 13 and later

  • SuperNova: Version 13 and later

  • Window-Eyes: Version 8.2 and later

  • ZoomText: Version 10.1.5 and later
