You can either use sockets

Or you can use SWIG http://bedevere.sourceforge.net/

I went with the SWIG option. You will have to revise the typemaps in the 
.i file for Java. After that you can wrapper the gprolog interface 
behind Java classes to make it much easier to use. It requires a little 
bit of hackery in some places (if anyone knows I'd still love to know 
how to create a choice point without resorting to Pl_Query_Begin). But 
it has been working quite well for me using GNU Prolog 1.2.17 (1.2.16 
fails in some places).
