JPL is a set of Java classes and C functions providing an interface between Java and Prolog.

JPL is a set of Java classes and C functions providing an interface between Java and Prolog. JPL uses the Java Native Interface (JNI) to connect to a Prolog engine through the Prolog Foreign Language Interface (FLI), which is more or less in the process of being standardized in various implementations of Prolog. JPL is not a pure Java implementation of Prolog; it makes extensive use of native implementations of Prolog on supported platforms.

JPL is designed in two layers, a low-level interface to the Prolog FLI and a high-level Java interface for the Java programmer who is not concerned with the details of the Prolog FLI. The low-level interface is provided for C programmers who may wish to port their C implementations which use the FLI to Java with minimal fuss. http://www.swi-prolog.org/packages/jpl/java_api/index.html
