JAB will be in their version of JDK which they will need to access the
software if they use Jaws or NVDA.
JAB is a part of Java and not a part of your personal code.

thank you all the problem was in the windows 32 file that should be copied to folder c windows32 sys64 the names aren't correct but it gives the meaning
the question now that if i send a compiled program to friend or publish it to the blind they should install jab or it will be in the compiled file

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

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.

thank you for helping
what is Java Access Bridge
i have windows 8.1 64 bit
and please explain to me the difference between swt
and swing i understand from messages that swing works
with jaws but why it didn't work with me and why i'll
need Java Access Bridge
and what about swt it can work with screen readers?
