Hi,
thank you for your post and your kind words.
I assume that you are using QtFuzzyLite to design your controller and from there you obtained the FLL code.
In Java, could you please export your engine to FLL and make sure that it is the same controller as the one you designed?
You can export in Java as follows: new FllExporter().toString(engine); or perhaps engine.toString() would do the trick too.
Cheers.
