Hello to all those interested in and adept at Jaws scripting and programming
for screen readers in general. I have experienced an issue trying to
upgrade from Windows 32-bit to Windows 64-bit that has me stuck and am
hoping some smart folks can help. Any comments and suggestions you make
will be heartily appreciated. Just so you know, the jobs of 7 people are at
stake.
ISSUE: Using Jaws For Windows version 14.0.9006, we have custom scripts for
a proprietary Java-based 32-bit application that work in Windows Enterprise
32-bit, but will not work in Windows Enterprise 64-bit. We are using the
default voice Eloquence in all environments.
BACKGROUND: The custom JFW scripts were created using JFW 13.0.303 on a
Windows Enterprise 32-bit machine. The scripts were tested extensively and
all worked as expected. The compiled binary file (.jsb) was loaded into JFW
14.0.9006 when the update was installed. In the 32-bit OS, the custom
scripts worked as expected.
These custom scripts were built to support QIK, a Java-based 32-bit
application. Java Access Bridge was installed using steps from both Freedom
Scientific and Oracle support sites. We have tested the Windows 32-bit
installation on several machines and all of the custom scripts function as
expected. Java Access Bridge was also installed on the 64-bit, per the
instructions provided by Oracle. We have checked to ensure the appropriate
.dlls are in the WOW64 AND WIN32 directories.
We are currently migrating to Windows Enterprise 64-bit operating
environment. After installing JFW 14.0.9006 x64, the custom .jsb was added
to the shared files directory in the same manner used on the 32-bit machine.
The customization did not work in the 64-bit environment. Specifically at
issue are the Java table functions: NavigateJavaTable (int UnitMovement)
and Function ActiveItemChangedEvent (handle curHwnd, int curObjectId, int
curChildId, handle prevHwnd, int prevObjectId, int prevChildId). The
default functions for JFW 13.0.303 was used to build the custom script that
supplied additional instructions for the QIK application. Again, these
scripts function properly in the 32-bit environment..
TECHNICAL INFORMATION:
Windows Enterprise 32-bit Environment (Jaws custom scripts work well in
this environment)
Java version jre1.6.0_21 (required for our version of Qik)

JFW 14.0.9006 32-bit
Windows Enterprise 64-bit Environment (Jaws custom scripts DO NOT work in
this environment)
Java version jre1.6.0_21 (required for our version of Qik)
Java Access Bridge version
JFW 14.0.9006 64-bit
