If Java 8 is installed then distributing the jar is the simplest solution as the new notarization requirements in MacOS make it quite difficult to distribute apps.

I think someone asked me more or less the same thing but for Windows.

In Windows, in order to run the jar, I think it is necessary that there is a system variable that points to the java 8 path. In my PC:



I suppose there is something similar in Mac too.

Or (Windows) use a bat file (still using java 8).


Sorry if I wrote nonsense, I've only seen Macs in photos ?

That's probably the problem. Try Java 8.

I recommend B4Jpackager11. It includes all necessary java stuff in one container. So your app will run on any Mac independently of whether Java is installed or not.
You can use Platypus to pack your app as a standalone Mac app with its own icon. If you want to distribute your Mac App through the internet, then you need to sign it. In case you need this feature, here some information (from last year, I didn't need to sign an app since then): http://www.zarkonnen.com/signing_notarizing_catalina
For an example you can see my app and install it: https://www.app-art.ch/downloads/mac/R3/GiroScanBase_v110.dmg

Cari saluti
David
