Java（classpath相对路径）和（document相对路径）之间的区别？

Question

Description

I am trying to understand what the above means.I have a project with the below schema:

~~->And here is an image from the SceneBuilder :

The problem

First i want to access the image1.png using ( document relative path ) which i think it is ../../resources/images/image1.png and then i want to access image2.png using ( classpath relative path ) which i have no idea what it means.

Finally

1. I want to be soore that when i export the application as a .jar file the images which are inside the .jar files are shown as they are shown when i open the application in Eclipse.

2. This is actually about Java 9 .I have to change anything so the project is running smoothly with Java 9 ?Will even .jar files be accepted?I am curious for that.

Thanks for the effort.

Answer 1

Classpath relative means the path will be relative to the classpath of the classloader used for loading the fxml file. You most likely do not want to use this option. Instead the document relative path: since src is not exported in to the jar, in Main.fxml this should be

@../images/image1.png

or

@../resources/images/image1.png

depending on eclipse storing the resources in a resources directory in the jar file or not. (Note SceneBuilder automatically adds the @ , if you select the appropriate option.)

As java 9 is concerned, I cannot tell you for sure, but the documentation contains a constant for the @ prefix so it's unlikely that document relative paths are removed in java 9.
