I have a fully-working JavaFX application that is currently distributed only as a runnable JAR. What I now need is a set of native installers/launchers for Windows, macOS, and Linux that ship with their own embedded JRE 8 so users can double-click and run without any manual setup. (jpackage, Launch4j + Inno, AppImage, etc.) prefered https://www.searchgurbani.com/sgdv/isg has the app compiled with install4j in 2018 Key requirements • Each platform gets its own launcher/installer that points to the bundled JAR and hides the Java console. • The launcher must accept –Xmx and –Xms parameters; I don’t have final numbers yet, so I’ll rely on your recommendation for sensible defaults and a clear place in the config where I can tweak them later. • Custom icons per OS (ICO, ICNS, PNG/SVG as appropriate) and a simple preferences dialog that persists settings to disk. (Have the images) • No external download of Java at runtime—JRE 8 is included within every build. • Outputs should install cleanly on Win 10/11, macOS 13+, and common Linux distros (Deb/ RPM or AppImage). • Final hand-off includes the installer files, source project for the packaging script, and a short read-me showing how to rebuild when the JAR changes. If you have experience squeezing maximum compatibility out of Install4j or similar tools and can advise on memory footprints, I’m ready to get this wrapped up quickly.
