Now, you will see how to download a JPL library, and how to interface with Prolog using JPL in Java.
In your browser, go to http://www.java2s.com/Code/Jar/j/Downloadjpljar.htm:
This is one of the popular repositories of all of the known JAR files that have been created, and it preserves all of those JAR files.
