Thanks :) I got my error. Because I declared my code as a class, my mind turned into a object logic and I forget I was always in Clojure and in functional mind.
I'd like understand an another point too. When I generate a jar with lein uberjar, the code works. But if I do only a lein jar, the running failed with a NoClassDef exception. Even if when I run the jar I use the java command's option -cp to give the jfxrt.java's place. Do I forget something?
