FXML layout not loaded when run jar outside Eclipse

Question

I try to load my fxml layout file as follows:

 FXMLLoader loader = new FXMLLoader();
 loader.setLocation(getClass().getResource("view/MainLayout.fxml"));
 AnchorPane personOverview = (AnchorPane) loader.load();

When I run application in Eclipse all works, but when I deployed application with Ant, I've got an error:

After building project my folder structure is:

and the same in deployed jar

I understand that there might be a problem with difference in resolving path inside jar and in eclipse, but I can't resolve this. I use Java 1.8 and JavaFX 8.

UPDATE 1 Accodring to the error I think it resolves path using absolute URL (starts with file:/C:/...), but should use relative url inside jar file. Why it use absolute path is main question.

UPDATE 2

Interesting that root layout loads successfully, with same code..

FXMLLoader loader = new FXMLLoader();
loader.setLocation(MainApp.class.getResource("view/RootLayout.fxml"));
rootLayout = (BorderPane) loader.load();

But inner layout initialization fails.

Answer 1

I am using following code

 FXMLLoader loader=new FXMLLoader(Main.class.getResource("views/MainFrame.fxml"));
 AnchorPane rootpane=(AnchorPane) loader.load();

and it is working as it should

edit : after looking at your trace I think problem is in your controller , try having a look at this link
