Hiba a házifeladat futtatása közben

Question

A házi feladatban még nem változtattam semmit (nem akarta megtalálni a javafx-et, de azt megoldottam) és amikor próbálom elindítani a következő hibaüzenetet kapom:

Comments

Ez mit jelent:
"nem akarta megtalálni a javafx-et, de azt megoldottam"

---

Az eclipse nem találta a javafx-es függvényeket és ezért hozzáadtam a preferences->Installed JREs alatt a kijelölt jdk-hoz a mappájában levő jfxrt.jar fájlt.

---

Letöltöttem a legújabb jdk-t, és azzal ezt a hibát kapom (itt már nem volt baj a javafx megtalálásával):

Feltelepíttettem egy linuxos virtuális gépet, azon működik.
