Hi,

That message already points out a lot of things that don't match. I'll
paste it here and add my comments.

Hi Florian,

Not to discourage you, but to my knowledge the popular Java IDEs are
not accessible when it comes to creating GUI applications, so even
after managing to setup the JAB and Java IDE you won't be much further
(unless you have some sight or sighted assistance) if you want to
create GUIs.
// I have heard eclipse is actually very accessible, and netBeans is
being worked on as we speak.

If you are going to work in a team with sighted peers then have them
develop the GUI and you focus on database and non visual components.

It is of course also entirely possible to code a GUI with a text
editor and the JDK alone. This would be a good option if you are going
to work alone on a project, but if you are in a group it might not
work too well since the other guys will most probably use an IDE.
// Are the days where we had to use swt for our gui's to be accessible
 over? Can default javax.swing classes be used if the java access
bridge works properly?

That said, here is my setup which enables the JAB on my Win XP Pro SP3 machine:
1. Make sure that the bin directory of the JRE you wish to use is
actually in your PATH environment variable.
/* It was not. I have now added c:\program files\java\jdk1.6.0_23\bin
to that environment variable. However, when scouring these environment
variables i found out something else that would cause trouble.
The classpath variable has the value:
.;C:\Program Files\QuickTime\QTSystem\QTJava.zip
I doubt that is right. Please copy your classpath variable's value
here so i know how to configure it correctly */

2. Make sure you have these files in the directory of the JRE:
C:\Program Files\Java\jre6\lib\ext\access-bridge.jar //check

C:\Program Files\Java\jre6\lib\ext\jaccess.jar // check
C:\Program Files\Java\jre6\lib\ext\jaccess-examples.jar // check
C:\Program Files\Java\jre6\lib\accessibility.properties // FAIL : that
file does not exist in that directory. Not to my knowledge at least.
That was the first thing i checked when referencing with the manual
installation instructions, it isn't there.
C:\Program Files\Java\jre6\bin\axbridge.dll // check

Note that you have to rename this file:
jaccess-1_4.jar
to:
jaccess.jar // I see no such file to rename, but jaccess.jar is already there.

3. Make sure you have these files in your System32 directory:
C:\WINDOWS\system32\WindowsAccessBridge.dll // check
C:\WINDOWS\system32\JavaAccessBridge.dll // check
C:\WINDOWS\system32\JAWTAccessBridge.dll // check

Hope this helps you,
Kerneels

It sure did. If you could tell me the correct classpath variable to
set and where to find this accessibility.properties file, it should
fix my problems.

Awaiting your response, thanks in advance,
Florian
