Do you mean that Java 6u21 is best for LibreOffice in general or does
the Java version also have an impact on accessibility? (I would not
know why it would have an impact but I'm asking just in case it does.)
After 24 LO might run into problems unless you are using LO 3.5.0
which is still not yet officially released but you might be able to
use the pre-release. The 3.5.0 can use java 7 at last.
Hopefully whichever java you are using is working fine but if there
are difficulties then checking the jave version might help
Tools - Options - Java
Yes, on Windows and Linux. I learnt recently that on Mac OS, there
are no "Options..." under Tools; you need to go to LibreOffice ->
Preferences... But I digress, since this was a Windows question.

Subject: Re: [libreoffice-accessibility] configuring libreoffice for
Date: Wednesday, 8 February, 2012, 19:58
Some configuration is necessary, but:
1) I don't know how easy they are to undertake with a screen reader, and
2) the benefit may not be what you expect.
My comment about the benefit of the configuration is that
LibreOffice accessibility on Windows relies on Java Accessibility,
which is not very well supported by screen readers. For better
results, LibreOffice would need a different accessibility system
called IAccessible2, but as long as OpenOffice.org has not
integrated this, LibreOffice can't or won't integrate IAccessible2
either (in order to avoid duplication of the same work).
Now to the configuration:
1. First, you need Java and the Java Access Bridge, which you
already have. However, if there is more than one Java Runtime
Environment on your machine, you need to make sure that the Access
Bridge is installed in the Runtime used by LibreOffice, or in all
your Java Runtime environments. You can check which Runtime
LibreOffice is using by going to the Options dialog (go to Tools
menu, then Options) and navigating to the Java pane; you need to
wait a few seconds while LibreOffice fetches the info about the
available runtimes. The list of runtimes also says if the Access
Bridge is installed in them. (If the text next to the vendor and
version info says: "with accessibility support", then the runtime
has the Access Bridge.)
2. After checking the runtimes and the Access Bridge, you need go to
"Accessibility" in the Options dialog (it is the item above or
before Java). The Accessibility pane contains a checkbox that says:
"Support assistive technology tools (restart required)". You need to
check this and restart LibreOffice.
However, because of the lacking support for Java Accessibility in
screen readers, some people use IBM Lotus Symphony instead. Lotus
Symphony uses IAccessible2 instead of Java Accessibility; it is free
but not open source.
Some people have compared JAWS and NVDA for accessing LibreOffice
and found NVDA somewhat better. You can download NVDA for free; if
you use the portable version, you can even run it from a USB stick
or your hard disk without an installation procedure (some unpacking
is needed, but nothing more).
I hope this helps.
