If you have time to spare you can take look at a this jni interface to 
octave.

http://www.d.kth.se/~bja/octavej.tar.gz

It shows how you can call an octave function by name and get the result 
back to java. It is based on the octave_embed example.

It's pretty primitive, for instance, it only supports real valued 
scalars and matrices. But it's easy to add new types, I think :-)

Also, values are copied from octave to java and vice versa, one should 
use java.nio buffers for sharing data instead.
