I wrote a mini project on java tested in intellijIDEA. Everything is working. Created a jar launched in Windows, everything works. Now I wanted to start from Linux (Kali if it matters), he gave me a decent error message:

As I understand the error occurs when trying to load fxml in the Main Class, here is the method code:

 Parent root = FXMLLoader.load(getClass().getResource("/sample/fxml/main.fxml")); primaryStage.setTitle("Crypter"); Scene scene = new Scene(root, 643, 431); primaryStage.setScene(scene); primaryStage.getIcons().add(new Image(getClass().getResourceAsStream("/sample/fxml/images/icon4.png"))); scene.getStylesheets().add(getClass().getResource("/sample/fxml/styles/configStyle.css").toExternalForm()); primaryStage.setResizable(false); primaryStage.initStyle(StageStyle.UNDECORATED); primaryStage.show();

Still, I would like to know what my joint is, Thanks in advance for any help :)

  • You collected a jarnik under 8 Java, and run on 9? - Andrew Bystrov
  • by 10 *, but does the path change there? - Eltsov Danil

You are missing the com.sun.javafx.css.StyleConverterImpl class in the class path. You need to find this class in the libraries and add the appropriate library.

  • Do not tell me how in intellij idea to find a class by name or you mean that it does not exist at all in java. I just put the full java 10 with of. site, I do not know why not roby - Eltsov Danil
  • If there is no class, then you cannot find it in the intellij idea. - Roman C

The most stupid mistake. I used jfoenix 8.0 library when using java 9. Now I downloaded jfoenix 9.0, everything worked
