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.

I ma using jaws 13.0.638 (beta), windows7 64-bit jdk 1.7.0U02 with
accessbridge 2.0.2, and I downloaded and installed libreoffice 3.4.5 yesterday.
After the installation completed, I tried using the libreoffice calc
program but jaws didn't read anything in the spreadsheet. I couldn't
even tell that I was in a spreadsheet.
Also jaws does not seem to be reading the menus properly, nor is it
reading any of the buttons in the tools -> options dialog.
Are there any things I need to do to configure libreoffice for accessibility?
