[nvda] Re: OpenOffice?

I think I understand what you are suggesting about interfacing to java apps, correct me if I am wrong.
You are saying bypass the java access bridge, and make a module for NVDA which interfaces directly with java, using the java accessibility stuff in java itself. You suggested jython, I understood jython to be another implementation of python, not an extension. This means, possible differences in the code, I think the information at the jython website says it is written to be at the code standard of python2.2, NVDA uses python 2.5. Another point is that they say jython can't take python extensions, so we would need a jython version of ctypes, the win32 extensions, pyhook, etc. The previous is true if I am right in that jython is a different implementation, and that trying to mix a python and jython app is not possible. If it is possible to mix the two, how much of an affect will this have on the rest of NVDA as you will have a java environment running as well?
I have never done programming in python to use the java accessibility, so I don't know what works well and doesn't, and if you have, and know that those concerns I have shown above aren't actually true, then say, I would have thought that trying to work with the java access bridge DLL would be better on what I know.

REPLY=> Sorry I was away yesterday to attend Windows Live Tech day.
Regarding java-access-bridge, things are done via JNI the native interface
which will add another havoc to NVDA. My advice is to use Jython or JPye as 
extension to NVDA and then load the java accessibility as module/package.
Interoperability, interprocess and bi-directional can be achieved without
struggling with path problems. They following links may help
1.) http://java.sun.com/developer/earlyAccess/jaccesshelper/ (Kit to aid in 
developing java-access-bridge -> generates interface codes)

2.)
http://www.oracle.com/webapps/online-help/jdeveloper/10.1.2?topic=ada_psetupacessbridge_html
(an implementation that could be modified for NVDA)

3.) http://prime.jsc.nasa.gov/MDE/ (Nasa java-access-bridge implementation
for teaching Maths to VIS and blind people. Industrial strength, work
out-of-box. Highly recommended if NVDA could interface with it since it is
made to work with screen readers.)

4.) http://www.jython.org/Project/index.html (Python in 100% Java. Highly
recommended as an extension for NVDA. So java-access-bridge will be plug-ins 
or loadable module or just turn the protected mode  off to public (could
done via registry properties as well)
5.) http://www.noodleglue.org/noodleglue/noodleglue.html (Another java glue 
with accessibility implemented -> Generates stub code for many languages
like SWIG)

6.) http://udk.openoffice.org/ (UNO openoffice.org is a interoperability
protocol between programming languages and has python, java ... glue code.
Used in Openoffice java-access-bridge as well)
My advice is to use Jython which will work well natively with NVDA and there 
would be no need for downloading or installing any java-access-bridge for
any platform unless a feature is missing. MDE is equally good but may
require modification to the interface to work with NVDA. There is a sample
for JAWS for Windows which could be adapted for NVDA. Both Jython and  MDE
could extend NVDA.

Hope this help!

Stay blessed!!!

My regards,
Sanyaade

Hi Sanyaade,
We need to figure out how to interface with the Java Access Bridge, not
how to interface with SAPI from Java. NVDA handles the speech stuff
separately. I haven't checked out these links yet, but I think most of
them relate to using SAPI from Java, rather than interfacing with the
Java Access Bridge from Windows. Thanks for the research, though - keep
up the good work.
