Hi :)
Hmmm, i meant the java 6u21 is best for LibreOffice generally and only for versions of LO that are 
prior to the 3.5.0 release.  It's also only from what people have said on the Users List.  Only 1 
or 2 people did any extensive testing so it's not exactly a water-tight report based on extensive, 
rigorously testing!  

No-one on the Accessibility List has mentioned about 1 version being better than another so far.  
So, we have even less to go on but it might be worth a try if it's easy.  
Regards from
Tom :)

Apparently the best version of java is the 6u21 version. The 20 and 22 are next best.

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 

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.

Best regards,

Hello Don,

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 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 

I hope this helps.

Best regards,

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?
