The Java Access Bridge version 1.0 is a technology where the Java Accessibility API, commonly known as JAAPI is exposed in a Microsoft Windows DLL. This actually makes the Java applications and applets where JAAPI is implemented, visible to the technologies on Windows. The Java Access Bridge is actually a class containing ‘native methods’. The DLL or Dynamically Linked Library on the Microsoft Windows System supplies a part of the code for this class. Java Access Bridge 1.0 is designed to work with Java 2 SDK v1.3. In order to obtain Accessibility information from a Windows HWND, JDK 1.1.8 and Java 2 SDK 1.2.2 have introduced a new mechanism which is required by the Java Access Bridge 1.0. One major problem is that this technology is not available in previous releases of JDK 1.1.x or Java 2 SDK 1.2.x. Since Java Plug-in version 1.1, 1.1.1, and 1.1.2 are based on previous versions of JDK 1.1.x (prior to JDK 1.1.8), so are not compatible with the Java Access Bridge 1.0. However, as the Java Plug-in 1.2.2 is based on Java 2 SDK 1.2.2, so is compatible with Java Access Bridge 1.0.
The package of Java Access Bridge 1.0 contains three editions of Java Accessibility Utilities file ‘jaccess.jar’, named jaccess-1_1.jar, jaccess-1_2.jar, and jaccess-1_3.jar. One important thing that should be noted is that, you need to add the ‘AccessBridge-1_0’ directory to your path, in order to find and instantiate the two DLLs that are part of the Java Access Bridge 1.0. more
