B4J Question [ABMaterial] Problem deploying to a Raspberry Pi

[janderkan]

I have OpenJDK11 on my PC and on the first deployment i got an error that my jar was built to a newer version.

Then I followed instructions in this link and installed bellsoft jdk11 on the Pi
ABMaterial did not run and the errors was

/js/core.4.30.min.js
Not Found
/js/sessioncreator.js
Not Found
/css/materialize.4.26.min.css
Not Found

I started all over with a new SD card and installed openjdk-9 using this command:

apt-get install openjdk-9-jdk-headless

Everything works fine.

To be sure I started all over with a new SD card and installed bellsoft jdk12 on the Pi
Exactly the same error again.

I use ABMaterial on a USB Stick myself and I set the SD card up as a root filesystem as Read Only following Adafruits tutorial. This way you can get spontaneous power losses and it wont corrupt the SD card.

However, I cant launch ABMaterial from any other directory except being CDd into ABMaterial or youll get all those same file errors. And this is using Liberica Java 8 from the tutorial that was up a year or so ago.
