Tim,
I suggest that you consider using Com4J.
I've not used it but have looked at its source code which is well written.
There's a tutorial at https://github.com/kohsuke/com4j/blob/master/src/site/markdown/tutorial.md.

P.S. There are two versions of FSApi: one for 32-bit and the other for 64-bit processes.

Subject: Re: [nfbcs] Help with Jaws API for Java project
So, I am having a really tough time getting java to work with ms com objects. A lot of the documentation is old. Does anyone know how to work with com objects in java, or can someone shed some light on my issues with using the FSAPI.dll.
Also, thank you for the path to the dll , however , I did see that one, there is also anFSAPI.dll in :
C:\Program Files (x86)\Freedom Scientific\Shared\FSAPI\1.0
I am not sure if this is different or if this is the 32 -bit version.
I do need both the 32 and 64 bit dlls though.
