Eclipse is working fine inside the container and its window is visible on the host (with the X11 being shared through socket).

The app is an Eclipse RCP project using JavaFX (Efxclipse and M2Eclipse). I removed all the references for the RCP below to have less complexity in the example and because it happens with really simple JavaFX apps (non-OSGI) as well - so OSGI isn't the issuer.

The following fatal error is happening when running a JavaFX GUI app inside Eclipse (inside a Docker container). 

#

Host details:

  • Ubuntu 16.10
  • Docker version 1.12.3, build 6b644ec

Container details:

  • Ubuntu 16.04
  • Oracle JDK 1.8.0_111 64bits
  • Eclipse Luna (RCP 4.4.2) with e(fx)clipse 1.2.0.201501301049
  • Dockerfile

Code for the JavaFX app:

package application;

import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.layout.BorderPane;
import javafx.stage.Stage;


public class Main extends Application {
    @Override
    public void start(Stage primaryStage) {
        try {
            Scene scene = new Scene(new BorderPane(),400,400);
            primaryStage.setScene(scene);
            primaryStage.show();
        } catch(Exception e) {
            e.printStackTrace();
        }
    }

    public static void main(String[] args) {
        launch(args);
    }
}

Although I had success running a simple GUI app using Swing:

package application;

import javax.swing.JFrame;
import javax.swing.JLabel;

public class Test {

    private static void createAndShowGUI() {
        JFrame frame = new JFrame("Test");
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.setSize(500, 500);
        JLabel label = new JLabel("Test");
        frame.getContentPane().add(label);
        frame.setVisible(true);
    }

    public static void main(String[] args) {
        javax.swing.SwingUtilities.invokeLater(new Runnable() {
            public void run() {
                createAndShowGUI();
            }
        });
    }
}

and this lead us to some problem related to JavaFX.

Even running an exported JavaFX app (as a Jar file) on the console (outside Eclipse) it's returning the same error.

Ideas on how to solve it and have the JavaFX app running inside Eclipse in the container?

Thanks

  • Possible dup: http://stackoverflow.com/q/16296753/18157 - Not dup-hammering because I don't know Docker enough to tell if it answers the OP's question. – Jim Garrison Jan 13 '17 at 03:44
  • Thanks for commenting @JimGarrison but it's not duplicated/same case. Eclipse is running well inside the container (sharing the X through socket). The problem is only with the JavaFX app.. – wcomnisky Jan 13 '17 at 03:59
  • The crash Problematic frame:# C [ld-linux-x86-64.so.2+0x9d20] shows it is more of glibc issue, point to the exact path and rerun your application – Fairoz Jan 20 '17 at 09:03
  • @Fairoz thanks for the reply but I didn't get it. I already have the solution and I'm gonna update the post with it.. – wcomnisky Jan 25 '17 at 02:12

The problem was related to few missing dependencies in my Ubuntu image. Without them I was not able to run JavaFX apps in a Docker container.

Installing the following packages solved the problem:

gtk2-engines
libswt-gtk-3-java
libxslt1.1
libxtst6
libxxf86vm1

I tried to install only one or two of them (a sort of combination) in an attempt to find out which one exactly is needed but it turned out to be time consuming so I'm installing all of them - for now.

I found the solution on this Dockerfile when searching for examples on Github. Thanks Patrick Martin.
