or for a developer distribution


I hope that JWin helps to open up more Java applications on Windows by making it easy to add accessibility support. More info about the program is below, including a link to the full documentation.



JWin is a free, open source program for detecting and installing the Java Runtime Environment (JRE) on Windows, together with the Java Access Bridge (JAB), which is needed for full accessibility of Java-based applications to assistive technologies used by persons with disabilities.

After confirming user intent, the program will create a directory containing JAB reference material, a log file, and an uninstallation program to later remove the JAB, if desired. It looks for locations of the JRE and offers to install the JAB into them. Three possible directories are identified: (1) the directory of a 32-bit JRE; (2) the directory of a 64-bit JRE; and (3) the directory referenced by the JAVA_HOME environment variable.

The program will open a log file when complete, detailing the actions taken. The JAB may be installed into any JRE location on the computer by first setting the JAVA_HOME environment variable to point to the relevant directory before running the executable.

If no JRE is found by the program, it will offer to go to the web page for installing Java.

Full documentation for this program is also available online at
