Hi Tim,
some random notes:
You can specify a native library location for jars in eclipse in the build path settings.
For deployment either put them in /Library/Java/Extensions or explicitly specify the location (I don't have example code for that at hand).
You can generate the headers with ant's javah task, but I remember running in some problem with that at some point, but I don't remember what it was... I ended up generating via CLI.
You should really take a look at using JNA (https://jna.dev.java.net/), this can replace much of the boilerplate code and the generated headers!
When you're interfacing with ObjC libraries, take a look at Rococoa (http://code.google.com/p/rococoa/).
There's also some tool that auto-generates JNA/Rococoa code from C headers called JNAerator (http://code.google.com/p/jnaerator/). It had some problems when I looked at it, but this is quite a while ago.
HTH,
Timo
