My Apologies, I sent the last email only to Glen.
Thank you for the resource Glen. I looked into com4j, and I think it
could help. It looks like I have to generate a type library from a com
library, then from that, I can generate the java classes that I can
import as normal. Is the FSAPI.dll the com library? How do I generate
a type library?
For java, this seems like a lot of work to access com objects, it
seems to me that it would be easier to work through the java native
interface and the dll. Can't I access the Jaws API through the dll,
the same way I am accessing NVDA's API, just by including the dll in
with my package, and calling into it from my code?
I see why it would usually easier to access jaws through the com
object most of the time, but when dealing with a language like Java
that doesn't make it easy, it seems like less of a headache, and less
overhead to just work through the java native interface.
Also, My only references for the Jaws API are the link I mentioned in
my first email and a python library that is accessing the Jaws API
(accessible_output2).
Is there official documentation on the Jaws API?
Thanks,
TJ Breitenfeldt
