FYI, you can quite easily bi-directionally make calls between Java and SWI-Prolog if you use JPL:

It is also fully re-entrant, so you can instantiate prolog code from java, which in turn instantiates java code etc...

I did this for a number of commercial projects a few years ago when I was required to connect a Prolog based Reasoning Engine to a lot of Java code.

It does use JNI (the Java Native Interface), so you need to be careful about how you compile and link to the native api. Though if you compile it appropriately for each platform you can make it work cross platform. I had it working on OS-X, Windows, Linux & Solaris.
