Deploying JavaFX Applications on Windows, Mac, and Linux

Are you ready to take your JavaFX application to the next level? Do you want to deploy your application on Windows, Mac, and Linux? If so, you've come to the right place! In this article, we'll show you how to deploy your JavaFX application on all three platforms.

Prerequisites

Before we get started, you'll need a few things:

• A JavaFX application
• A Java Development Kit (JDK) installed on your computer
• A JavaFX SDK installed on your computer
• A build tool such as Maven or Gradle

If you don't have these things already, don't worry! We'll walk you through the process of getting everything set up.

Setting Up Your Environment

The first thing you'll need to do is install the JDK and JavaFX SDK on your computer. You can download the latest versions of both from the Oracle website.

Once you've installed the JDK and JavaFX SDK, you'll need to set up your environment variables. On Windows, you can do this by going to Control Panel > System and Security > System > Advanced system settings > Environment Variables. On Mac and Linux, you can set environment variables using the terminal.

Here are the environment variables you'll need to set:

• JAVA_HOME: This should point to the directory where your JDK is installed.
• PATH: This should include the bin directory of your JDK and JavaFX SDK installations.

Building Your Application

Now that your environment is set up, you can build your JavaFX application. If you're using Maven or Gradle, you can use the javafx-maven-plugin or javafx-gradle-plugin respectively to build your application.

Here's an example pom.xml file for a Maven project:

<build>
    <plugins>
        <plugin>
            <groupId>org.openjfx</groupId>
            <artifactId>javafx-maven-plugin</artifactId>
            <version>0.0.7</version>
            <executions>
                <execution>
                    <id>default-cli</id>
                    <configuration>
                        <mainClass>com.example.Main</mainClass>
                    </configuration>
                </execution>
            </executions>
        </plugin>
    </plugins>
</build>

And here's an example build.gradle file for a Gradle project:

plugins {
    id 'org.openjfx.javafxplugin' version '0.0.10'
}

javafx {
    version = "11"
    modules = [ 'javafx.controls', 'javafx.fxml' ]
}

mainClassName = 'com.example.Main'

Once you've built your application, you should have a JAR file that contains all of your application's dependencies.

Creating a Native Installer

Now that you have a JAR file, you can create a native installer for your application. This will make it easier for users to install and run your application on their computers.

There are several tools you can use to create a native installer, including:

• Inno Setup (Windows)
• DMG Canvas (Mac)
• Install4j (Windows, Mac, and Linux)

In this article, we'll focus on using Install4j to create a native installer for all three platforms.

Installing Install4j

You can download Install4j from the ej-technologies website. Once you've downloaded and installed Install4j, you can launch it and start creating your installer.

Creating a Project

To create a new project in Install4j, click on File > New Project. You'll be prompted to choose a project type. Choose "Installer" and click "Next".

Next, you'll be prompted to choose a platform. Choose "Multi-Platform" and click "Next".

Configuring Your Project

Once you've created your project, you'll need to configure it. Here are the steps you'll need to follow:

1. Add your JAR file to the project. To do this, click on "Add Files" in the "Files" section of the project tree and select your JAR file.

2. Configure the Java Virtual Machine (JVM) options. To do this, click on "VM Options" in the "Installer" section of the project tree and enter the following options:

   -Djava.library.path=$INSTALL_DIR$/lib
   -jar $INSTALL_DIR$/yourapp.jar
   

   Replace yourapp.jar with the name of your JAR file.

3. Configure the installation directory. To do this, click on "Installation" in the "Installer" section of the project tree and enter the following directory:

   $INSTALL_DIR$/yourapp
   

   Replace yourapp with the name of your application.

4. Configure the shortcuts. To do this, click on "Shortcuts" in the "Installer" section of the project tree and add shortcuts for your application.

5. Configure the splash screen. To do this, click on "Splash Screen" in the "Installer" section of the project tree and add a splash screen for your application.

6. Configure the license agreement. To do this, click on "License Agreement" in the "Installer" section of the project tree and add a license agreement for your application.

Building Your Installer

Once you've configured your project, you can build your installer. To do this, click on "Build" in the toolbar and choose "Build Project".

Install4j will create a native installer for each platform you've selected. You can find the installers in the output directory of your project.

Conclusion

Congratulations! You've learned how to deploy your JavaFX application on Windows, Mac, and Linux. With a little bit of effort, you can make your application available to users on all three platforms. Happy coding!
