This is not the source code for the JavaBayes API but a compiled jar file for use within projects.
If you want to look at the source code please refer to either: JavaBayes Original Codebase or JavaBayes for Java 1.6 and above (which is what this compiled jar is based on).
I've not altered their code in anyway but merely compiled and exported a jar file for others to use if need be.
