[nfbcs] BlueJ and JAVA Access Bridge

[Nicole Torcolini]

The JAB is needed when a Java application uses the graphics library  that
comes with the JRE or JDK. If the application uses the swt library or is a
command line application, then the JAB is not needed. I seem to recall that
the swt library was not very popular amongst sighted programmers because of
certain problems with it. Please let me know if you have any problems
enabling the JAB.

Subject: [nfbcs] BlueJ and JAVA Access Bridge

Good evening everyone,

    This afternoon I downloaded and installed a program called BlueJ that is
used to develop applications using JAVA. When I launched the editor I could
not do anything with it. Exploring their Web site further I discovered that
screen reader support is built in but one needs to enable the JAVA Access
Bridge (JAB) to use BlueJ with a screen reader. The process for doing this
was outlined and I expect to do this over the next few days. My question is
that if the JAB is required to use BlueJ will the resulting applications
created using this IDE also require the JAB so blind users can access them
with a screen reader? It seems like this question has come up here before
but I can't remember the rules of when the JAB is needed and when it is not
to use applications developed with JAVA?

 In a class I took in the early 2000's we used JAVA as our programming
language. We used TextPad for the editor pared with the JDK without the need
for a helper application such as the JAB. A refresher on when the JAB is
necessary for using JAVA apps with screen readers and when its use is
unnecessary will be very much appreciated.
