Introduction

JavaFX is a software platform for creating and delivering desktop applications and rich Internet applications (RIAs) that can run across various devices. JavaFX is intended to replace Swing as the standard GUI library for Java SE, but both will be included for the foreseeable future. JavaFX has support for desktop computers and web browsers on Microsoft Windows, Linux, and macOS.

There are three main components in the JavaFX runtime:

• The graphics pipeline, which is an implementation of the Prism rendering engine that supports Direct3D and OpenGL on Windows and Linux, and OpenGL on macOS;
• The media stack, which is based on GStreamer and provides support for playing audio and video;
• The web stack, which is based on WebKit and provides support for HTML5 features.
  What are the Javafx Runtime Components?
  
  The Javafx Runtime Components are a set of libraries that allow JavaFX applications to run on your computer. If you are receiving this error, it means that your computer is missing some of these components and they need to be installed in order to run the application.

There are a few different ways to fix this issue:

-Install the OpenJFX Runtime Components: The OpenJFX project provides a set of freely licensed open source jars that contain the necessary JavaFX runtime components. You can download these from the OpenJFX website (https://openjfx.io/).

-Install the Oracle JavaFX Runtime Components: If you want to use the Oracle versions of the JavaFX runtime components, you will need to download and install them from the Oracle website (https://www.oracle.com/java/technologies/javafx/). Note that you will need an Oracle account in order to access these downloads.

-Use a JavaFX Application with an Embedded JRE: Many JavaFX applications come bundled with a private version of the Java Runtime Environment (JRE). This means that all of the necessary Javafx runtime components are included with the application and do not need to be installed separately.

How to fix the Javafx Runtime Components Error?

If you see the error message “Error: Javafx Runtime Components are missing and are required to run this application” when launching a JavaFX application, it means that the runtime components required to run JavaFX are not installed on your system.

There are two options to fix this error:

Option 1: Install the JavaFX SDK

Download the latest version of the JavaFX SDK from the Oracle website. Once downloaded, unzip the file and add the javafx-sdk/lib directory to your system path. This will add all the necessary jars to your classpath and allow your application to launch successfully.

Option 2: Use a JavaFX-enabled JDK

Alternatively, you can install a JDK that comes bundled with JavaFX. This is the recommended approach as it will ensure that you always have a compatible version of JavaFX installed and don’t have to worry about manually adding jars to your classpath.

Oracle provides two different types of JDK bundles – one with Oracle’s own implementation of Java, and one that uses OpenJDK. The Oracle JDK bundles come in two flavours – with and without commercial features. The OpenJDK bundles do not contain any commercial features by default but some vendors (such as Azul) offer OpenJDK builds with commercial features included.

So, if you want to use Option 2, you have three different choices of JDK to choose from:
-Oracle JDK with Oracle’s own implementation of Java and commercial features enabled by default
-Oracle JDK with Oracle’s own implementation of Java and commercial features disabled by default
-OpenJDK with OpenJDK as the implementation ofJava and no commercial features by default (although these can be added via a third-party vendor such as Azul)

Conclusion

JavaFX is a software platform for creating and delivering desktop applications, as well as rich Internet applications (RIAs) that can run across a wide variety of devices. JavaFX is intended to replace Swing as the standard graphics toolkit for Java SE, but both will be included in Java SE 8 and continue to be supported.
