I cleared out the JavaVirtualMachines folder as you said, downloaded java 8 from both links, and now the server is up and running! Thank you guys, you've been a great help. ?

Do you know if there are any java executable programs or any guide on how to make one?

I tried downloading both HotSpot and J9 but the same error keeps coming up.

How do I set it on Java 8 or where can I download it?

This error message keeps popping up every time I try to open my launch.command and I don't know how to fix it.
