custom jre with javaFX 11

问题

I'm Using JDK11 and JavaFX11.
I created a custom JRE for my sample FX module program using Jlink, but when I try to run with the custom JRE, it renders errors as below:

This is how I created my custom JRE (no errors)

jlink --module-path ..\jmods;%PATH_TO_FX% --add-modules java.base,java.desktop,jdk.unsupported,javafx.graphics --output FXJRE

This is how I tried to run (with errors)

FXJRE\bin\java --module-path %PATH_TO_FX%;mods -m com.javafxdemo/com.javafxdemo.JavaFXDemo

The error messages:

Graphics Device initialization failed for :  d3d, sw

Here is How I compiled: The source JavaFXDemo.java

package com.javafxdemo;

import javafx.application.Application;
import javafx.event.ActionEvent;
import javafx.event.EventHandler;
import javafx.scene.Group;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.stage.Stage;

public class JavaFXDemo extends Application {
    @Override
    public void start(Stage stage) {
        stage.setTitle("Hello World");
        Group root = new Group();
        Scene scene = new Scene(root, 300, 250);
        Button btn = new Button();
        btn.setLayoutX(100);
        btn.setLayoutY(80);
        btn.setText("Hello World");
        btn.setOnAction(actionEvent -> System.out.println("Hello World"));
        root.getChildren().add(btn);
        stage.setScene(scene);
        stage.show();
    }

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

module-info.java

module com.javafxdemo {
    requires javafx.base;
    requires javafx.graphics;
    requires javafx.controls;

    exports com.javafxdemo;
}

This is how I compiled.

javac -d mods\com.javafxdemo --module-path %PATH_TO_FX% src\com.javafxdemo\module-info.java src\com.javafxdemo\com\javafxdemo\JavaFXDemo.java

After compilation, I have module class files as below:

├───mods
│   └───com.javafxdemo
│       │   module-info.class
│       │
│       └───com
│           └───javafxdemo
│                   JavaFXDemo.class
│
└───src
    └───com.javafxdemo
        │   module-info.java
        │
        └───com
            └───javafxdemo
                    JavaFXDemo.java

I can successfully run as below:

java --module-path %PATH_TO_FX%;mods -m com.javafxdemo/com.javafxdemo.JavaFXDemo

I can run with the default JDK11 though.

How can I successfully create a custom JRE and run the sample FX module program with it?

回答1:

If you go to this link, you will notice there are two flavors for the JavaFX distribution for each platform:

The JavaFX SDK is the one you are using as:

export PATH_TO_FX=/path/to/javafx-sdk-11/lib

and if you check the files under lib, these are jars.

The JavaFX jmods on the other side contains the jmod format.

And if you read about the jmod format here:

For most development tasks, including deploying modules on the module path or publishing them to a Maven repository, continue to package modules in modular JAR files. The jmod tool is intended for modules that have native libraries or other configuration files or for modules that you intend to link, with the jlink tool, to a runtime image.

In other words, if you use javac or java to run your jar or module you can use the SDK, but if you are using jlink to create a custom JRE, you need the jmod version.

Once you have downloaded the jmods, unzip them and create this variable:

export PATH_TO_FX_JMOD=/path/to/javafx-jmods-11/

Now you can create the JRE:

jlink --module-path %PATH_TO_FX_JMOD%;mods --add-modules=com.javafxdemo --output FXJRE

and run:

FXJRE/bin/java -m com.javafxdemo/com.javafxdemo.JavaFXDemo

回答2:

Ubuntu 18.04, Java 11, Netbeans 11.0: I had the same error as you because I set up Library JavaFX11 using the jars in /usr/share/openjfx/lib which are from the Ubuntu openjfx 11.0.2+1-1~18.04.2 package. I thought because the same jars were in this directory I could use it but the javafx-sdk-11.0.2/lib directory you get by downloading JavaFX Linux SDK from https://gluonhq.com/products/javafx/ contains many other library files (like libglass.so) which ARE needed.
