Hi Juan,
Yes, I’m using that file in my project.
1. I don’t get a compile error when I refer to a class in the jfuzzylite library.
2. There is also a jarfile jfuzzylite-src.jar, I’m using this file too (along with jfuzzylite.jar).
I get an error only when I run the program. It says that the classes in jfuzzylite.jar could not be found.
