By the way: one key problem when working is web start is that you have to modify all jars with the corresponding tags, which were listed in the beginning. This great hint makes it very easy to edit the jar files:

It was from michaelwarne at this forum: https://forums.macrumors.com/threads/how-to-modify-a-java-jar-file.1136993/

1. Navigate to the file location in the terminal.
2. Type vim name.jar
3. Select the file you want to change and hit "Enter"
4. Edit the file [e.g., by navigating to a line to be changed, then hit 's' for example, make then your changes] and press "Esc" and ":wq!" to save and quit. [One more time ":q!" to exit the jar file]

This great hint makes life so much easier!
