Running a Java GUI app from Flatpak Sdk with openjdk.

00_README.md

Run a Java GUI App without installing it from Flatpak Sdk

Overview

This is mostly because I didn't want to install Java on the system, and to learn more Flatpak stuff.

Requirements

• Flatpak

Setup

Install the following Flatpaks.

flatpak --user install flathub org.freedesktop.Platform//21.08
flatpak --user install flathub org.freedesktop.Sdk//21.08
flatpak --user install flathub org.freedesktop.Sdk.Extension.openjdk17

Usage

Becuase I have my Java JAR in the Downloads folder, I have to allow it. Then I also need to allow x11. To run the Flatpak do the following:

flatpak run --command=/bin/sh --filesystem=xdg-download --socket=x11 org.gnome.Sdk

Then enable the OpenJDK17 extension

source /usr/lib/sdk/openjdk17/enable.sh

Now we'll attempt to run the application.

[📦 org.gnome.Sdk worldographer]$ java -Djavafx.verbose=true -Dprism.verbose=true -Xmx4G -Dprism.maxvram=3G -jar worldographer.jar

Here is the error in full.
