Hi
I don’t know if the below is relevant to your difficulties but it has been a
common problem for a few years. If you check your NVDA log file and find a
message about Java access bridge (it’s usually found just before the ‘NVDA is
initialized’ message) this is symptomatic of the JAB 32-bit dll not being in
the right place, so read on.
For 64-bit Windows machines, you should install both the 64 and 32-bit versions
of the Java Runtime Environment (JRE), for 32-bit Windows machines, only the
32-bit JRE is required. Note: if you use the Java Development Kit (JDK), you
do not need JRE as the relevant DLL's are included however, JAB dll-s stil need
to be in the relevant folders, so please apply the rules below to get JAB to
work with your screen reader..
The Java installers are notoriously bad at putting files associated with the
Java Access Bridge (JAB) into the correct folders, particularly on 64-bit
Windows systems and it is sometimes necessary to do the task manually. Below
are the details for putting JAB files into the correct folders on Windows
systems.
64-bit Windows
1A. After installing both 64-bit and 32-bit JRE's, ensure the following dll
files are in the folders shown and are dated the day you ran the respective JRE
installation package:
Windows\System32\WindowsAccessBridge-64.dll
Windows\SysWow64\WindowsAccessBridge-32.dll
2A. If either/both dll is missing or has the wrong date, you can find them in
the following folders:
Program Files\Java\jrex.x.x_y\WindowsAccessBridge-64.dll
Program Files(X86)\Java\jrex.x.x_y\WindowsAccessBridge-32.dll
Where x.x.x is the Java version number and y is the java update number. You
may copy missing dll's from these locations to those locations detailed in 1A
above.
32-bit Windows
1B. After installing the 32-bit JRE, ensure the following dll file is in the
folder shown and is dated the day you ran the JRE installation package:
Windows\System32\WindowsAccessBridge-32.dll
2B. If the dll is missing or has the wrong date, you can find it in the
following folder:
Program Files\Java\jrex.x.x_y\WindowsAccessBridge-32.dll
Where x.x.x is the Java version number and y is the java update number. You
may copy the missing dll from this location to the location detailed in 1B
above.
Additional Note:
I have had a situation where I could not do a manual copy of a dll due to there
being an existing copy in the target folder, pre-dating the one I was wanting
to copy, which was currently in use so unable to be replaced. I quit my screen
reader and used Narrator to complete the copy process.
Cheers
Chris

SWT looks almost like old C/C++ code.

JAB is a piece of software to make Java work with Jaws and NVDA.
If you use either screen reader and Java then you must have it enabled or you
will not be able to access the Java program.
Making sure it is installed is good but you must make sure it is enabled.
This is like installing something then turning it on.
Swing and SWT are just different packages to create GUI.
It depends which you prefer to use and that is it.
Swing is made to be easier but for screen readers this is not true as it still
needs a bit of extra coding to make things accessible.
SWT is an older way to write GUI and might need more coding but is a bit more
reliable and less complicated.
That is my view of Swing and SWT.
