[Solved] Install jar making problems [Solved]

[MX_Starter]

Hi community,

I am new to this forum. Sorry in advance if I missed something.

I have a problem regarding this program. I use the nightly version from here: https://inf-didaktik.rz.uos.de/abbozza/ ... nstall.php You can find the github here. https://github.com/mbrinkmeier/abbozza-calliope
I suppose none of you ever used it before since it is work in progress. My problem is that: It seems I can install it regularly by executing the jar file. After pressing the short cut icon, which was added to the task bar, the shell script will be started and I will be asked which browser I want to start. However, then nothing more happens than an ever-loading webpage and an empty process window. From the log files I can see that the server is started and running, but it seems to be parsing/checking the html-file forever.
As required I installed yotta from pip and my java is openjdk-8. However, I don't know if this is related.
This software is running on other OSs. I don't want to change back to Ubuntu for this.

Does this happen for you also? Do you have any idea what I can try?
I am grateful for any kind of help.

Hey,
thank you for your reply and sorry for my late reply and also sorry for getting back to this topic. I just wanted to let everyone who might come here know that you need to install Oracle Java. Somehow OpenJDK is not able to substitute this.
Also thank you for pointing out some ways of how to handle these kind of problems

Best regards
