#39837 — cross-platform packaged app

Hey there

I’m currently planning on developing a UI App based on JavaFX for Win, 
Mac and Linux. The requirement would be that the app can be executed on these 
platforms without the user having to install a JRE. So the app must either be 
natively compiled or packaged with a JRE.

Is there anyone here who can share the best practice on how to do that?

- Louis

Java never has to be installed, you can download it and extract it and point the run as to the javaw.exe.
I'm not sure about the licensing for distributing the JRE. Packaging it with a download for in house app users in a zip should be simple enough.
When you download Java, it asks you what OS, so you would need separate downloads for each OS.
If you want something they can just run without extracting a folder and linking the Java exe to a jar file, you can build it all in an exe file for Windows (https://launch4j.sourceforge.net/). I don't know about Mac or Linux.

OpenJava packages are included in all the commonly used Linux 
distributions. They are entirely compatible with the equivalent Oracle 
releases and include the standard documentation and toolsets.

I have never tried any of it.

But you should probably investigate:
- JavaFX jlink with launcher
- Gluon substrate to create native image
