How to change Javafx default app image/icon/thumb

Question

I developed a javafx application. I want to change the java default icon of .jar file. I tried this primaryStage.getIcons().add(icon);

but this only make change the left top corner icon when running the app not the external view image.

All Jar files have the same icon and it depends on the OS to show an icon on a file depending on the file type.

primaryStage.getIcons().add(icon);

The above line will only get executed when a JVM is created for the application, so it doesn't make sense to depend on this particular piece code to display an icon :)

If you want to change the file icon, you will have to wrap the executable jar file to create a new native executable file (which depends on the OS). For example - EXE for windows. This new file will contain the image file to be displayed and the jar to be executed.

You can try using Launch4j or JSmooth for creating a wrapper file.
