A Java interface to SWI Prolog is available using JPL.

JPL is integrated into the full SWI-Prolog distribution starting with version 5.4.x, including binaries for MS-Windows and a Linux RPM. Documentation is -like all integrated packages-, available from the SWI-Prolog website (http://www.swi-prolog.org/packages/) and from the local manual browser under Help/Package documentation. Examples are included in the directory doc/packages/examples/jpl relative to the installation directory. These examples include embedding Prolog in Java as well as the other way around.

It is actively maintained by PaulSingleton.

Steve Moyle compiled instructions for getting JPL running on redhat. See JplOnRedhat.
