JavaFX load image from external folder

I need some help with importing Images to my JavaFx application:

My image has the path : /sprinter/ExternalSprinterFolder/Maps/map_asteroid/map_asteroid.jpg

My GUI code has the path: /sprinter/src/de/sprinter/gameclient/gui/SelectSectorGui.java

I tried already a lot but I can't load the image... I tried for example:

File file = new File(imagePath);
Image image = new Image(file.toURI().toString());
ImageView iv = new ImageView(image);

and

 String image = SelectSectorGui.class.getResource(imagePath).toExternalForm();
 pane.setStyle(("-fx-background-image: url(\" " + image +
                      " \");-fx-background-repeat: no-repeat;"));

Best How To :

The first code block is the correct way to do this if the file will be on the file system, and not bundled as part of your jar file. In that case imagePath should be the absolute filesystem path to the file. You can check if the file exists with

System.out.println(file.exists());

The second code block is the correct way to do this if the image file will be bundled in your jar file. In this case, imagePath should be relative to the class; an path starting with / is interpreted as being relative to the classpath. If the path is incorrect in this case, getResource(...) will return null.
