Using Java FX with TMC Beans - java

currently I am completing the Java II MOOC course of the University of Helsinki. Therefore I am using TMC Beans. In part 13 GUIs are introduced, so JavaFX is required.
However, importing from JavaFX is not working, e.g.:
import javafx.application.Application;
it says "package javafx.application does not exist."
There aren't really instructions in the course materials to solve this problem...
What I've tried so far:
Installing the Plugin "Java FX Implementation for Mac OS X"
Downloading the Java FX SDK for Mac and
Creating a new global library in TMC Beans, containing the paths to all of the jar objects in
the SDK
Putting the paths to the jar objects in the SDK on the used platform (JDK 14)
I'd really appreciate some advice!

Java II MOOC uses AdoptOpenJDK ver 11. Head over to https://adoptopenjdk.net/ and download that Java version. Then change your project structure to use AdoptOpenJDK.

You should look here: https://programming-f19.mooc.fi/macos-ohjeet
You need to add TMC Beans to the list of apps that have accessibility rights.

Openjdk-17.0.2 with javafx in termux

Hello I installed openjdk-17.0.2
In termux and I want to make a javafx application I start finding the sdk of javafx for java 17.0.2 but I got nothing. Can anybody tell how can I install the javafx for the openjdk 17.0.2. Or how can I install java 18.0.1 in termux because there is a option to download javafx sdk for java 18.0.1 but not for java 17.0.2.
For faster development and improvement, JavaFX was excluded from Java SE since OpenJDK 11, and now managed as a separate project (see https://github.com/openjdk/jfx). If you want to use JavaFX with Java SE, you need to download JavaFX jmods/SDK from https://www.gluonhq.com/products/javafx, and put them in module path / class path when building.
However, the official builds of JavaFX can't be used in Termux because the architecture is incompatible. There is already a package request in Termux's official packages Github repository (see https://github.com/termux/termux-packages/issues/10225), if this package is built and added into Termux, then you can install it simply by apt install openjfx and use it in your build.

NetBeans: "Failed to automatically set-up JavaFX Platform"

I have been troubleshooting this error for the past few days - and have hit a brick wall. I am running NetBeans v11.3, and Ubuntu Bionic (v18.04.4).
I have installed Java versions 8 and 11 (openjdk) along with source code.
I have also installed javaFx versions 8 and 11 with source code.
I have even gone to "Tools -> Java Platform Manager" and ensured that v8 and v11 of Java are properly installed along with the appropriate "Platform Sources".
But I still get the error mentioned when I try to create a new JavaFX project.
Any help would be very much appreciated.NetBeans JavaFX project create error
I have never tried to use JavaFX on openJDK, try out with Oracle JDK, as far as I know this is the best choice for using JavaFX, also try to edit the default platforms to match the appropiate system paths

Java 13: Why are javaFX runtime components missing?

Error Message: Error: JavaFX runtime components are missing, and are required to run this application
LOOK HERE: project structure photo
I have downloaded the javafx extentions for the project as well as the jar file and attached it, the program knows javafx is there since the code errors went away. However, it then said there were no docs and no it says there's no JavaFx runtime components. I have been hiting error after error trying to get javafx to just run a hello world program in eclipse.
JavaFX was removed from Java 11.
It's no longer shipped with the JDK, you need to install it separately (it's now a distinct product called OpenJFX).
JavaFX is no longer provided in the builds after Java 10; however commercial support for JavaFX in JDK 8 (LTS) will continue through at least 2022.
You can now use OpenJFX Project, which is the open source home of JavaFX development. It's sponsored by the Swing Group.

How to use JavaFX in jdk11?

I am a beginner programmer and now I want to start GUI applications in java.(as I previously worked on java too). I started reading some books on FX but its not compiling on JDK11 .. Do I need to use jdk8 or is there any way i can do it on jdk11 too?
JavaFX has become unbundled from JDK11 (both Oracle's official JDK and OpenJDK). In order to use JavaFX with JDK11, you'll have to download the standalone JavaFX11 runtime.

How do I use JavaFX 11 in Eclipse?

I have some trouble with JavaFX. I wanted to start creating apps, desktop or mobile, at least something. So I found out I could use the JavaFX library for it. But as far as I understood, it was excluded from JDK 9. I'm actually using OpenJDK 11 on Ubuntu 18 (though Eclipse writes I have the JavaSE 10 environment, that is where I'm also a bit confused) and I installed OpenJFX using sudo apt install openjfx and I can't make Eclipse work with JavaFX.
I'm not sure if there's any sense not to use JDK 8 with the included JavaFX, but anyway, how can I use JavaFX in such conditions in Eclipse?
There are multiple points in your post which needs clarification. I will try to answer them in different bullet points:
But as far as I understood, it(JavaFX) was excluded from JDK 9.
JavaFX will be decoupled from Oracle JDK starting JDK 11. I stress on Oracle JDK because JavaFX was never a part of OpenJDK. Not even in OpenJDK 8.
I'm actually using OpenJDK 11 on Ubuntu 18 (Though eclipse writes I have JavaSE 10 environment, that is where I'm also a bit confused)
For Java 11 support in Eclipse, you need to install
Java 11 Support for Eclipse Photon plugin.
Here are a few Examples on how to run Java 11 applications in Eclipse
I installed openjfx using sudo apt install openjfx and I can't make eclipse work with JavaFX.
I'm not sure if there's any sense not to use JDK 8 with included JavaFX, but anyway, how can I use JavaFX in such conditions in eclipse?
Since OpenJDK 11 or Oracle JDK 11 will not come bundled with JavaFX, your best bet is to either download the JavaFX SDK from here or here and load them in your IDE.
If you are used to build tools, you can directly use the JavaFX runtime jars which are available in Maven Central.
For a tutorial on how to run JavaFX 11 on OpenJDK 11, you can follow:
Getting Started with JavaFX 11
JavaFX on JDK 11
JavaFX 11 and Eclipse
At the time of writing this post, you need Eclipse 4.9M3 to work with JavaFX 11.
Once you have eclipse, JDK 11 and JavaFX 11 SDK, you can either opt to create:
Module based project
Non-module based project (No module-info.java required)
Module based Project
Create a Java project and add JavaFX jars from the Java FX 11 SDK to the module path of the project.
Create a module.info and declare its dependency of javafx.controls module. javafx11 is the name of the package which contains your Java file.
module javafx11 {
requires javafx.controls;
exports javafx11;
}
Run the program \o/
Non-module based Project
Create a Java project and add JavaFX jars from the Java FX 11 SDK to either the module-path or classpath of the project.
Add the following JVM args to the run configuration of the project:
--module-path=path-to-javafx-skd/lib --add-modules=javafx.controls
Run the program \o/
tl;dr
To most easily get started with JavaFX, use the Oracle-branded release of Java 8 where JavaFX 8 is bundled and easily available.
For technical details, see Using JavaFX in JRE 8. Look to the Linked and Related sections of the web page for many related postings.
Java Modularization
The Java platform is in the process of a sweeping reformulation, known as modularization.
Previously, Java SE (standard edition) was one big monolith of software, ever-growing with more and more being added. No single app ever uses all of it.
A decision was taken to break Java SE into many separate chunks to be defined formally as “modules”. One major benefit is that an app may be bundled with a Java SE runtime composed of only the modules actually needed, with unused modules omitted. See the jlink tool.
As a byproduct of this modularization, some older and less-popular parts such as CORBA are being dropped, to no longer be carried as a standard part of Java (though offered for other parties to pick up if they so decide). Similarly, some Java EE related modules will be removed from Java SE and turned over to the Jakarta EE project, logically a more appropriate home. See JEP 320: Remove the Java EE and CORBA Modules.
The process of modularization and reorganization is a years-long ongoing effort. Much was done in Java 9 and Java 10. Some of the final steps are being done in Java 11.
One of these steps being taken in Java 11 is to cease bundling JavaFX with Java SE. See:
The Future work section of the JavaFX Wikipedia page
The 2018-03 Oracle blog post, The Future of JavaFX and Other Java Client Roadmap Updates
The 2018-03 Oracle white paper, Java Client Roadmap Update
The curse, May you live in interesting times
So getting started with JavaFX development right now will be easiest if done with Java 8. The JavaFX libraries are bundled in with Java 8. And you need not learn about modularization, nor need to wrestle your IDE (such as Eclipse) and project settings to recognize modules. If you do not have a pressing need to use the very last versions of Java or JavaFX, stick with 8 until the modularization process and tools gets smoothed out, likely next year 2019.
If you insist on using Java 11, you need to learn about:
Java modularization in general, including the module-info.java file.
Updating your IDE (Eclipse, etc.) and other tools to later versions supporting both modularization and Java 11.
Configuring modules in your build tools, such as Maven or Gradle
Configuring modules in your IDE, such as Eclipse
Downloading JavaFX modules, or using a dependency manager such as Maven to do so
Those points are too much to cover here, and have been covered in many other Questions on Stack Overflow. Besides, Java 11 has not yet been formally released.
Perhaps this article will help, How to Create a Project With JavaFX on JDK 11.
To learn much more about Java modularization, read the blog and the book, The Java Module System, by Nicolai Parlog.
I've had to struggle through this on about 20 computers now, so I made the following checklist:
[ ] download javafx11 from javafx11's website, put on desktop
[ ] create a MODULE based project
[ ] right click project, go to BUILD PATH
[ ] add the downloaded javafx.base/control/graphics as external jar files
[ ] put the files in a package (eg: my_big_package)
[ ] put the following in the module.java file:
module javafx11 {
requires javafx.controls;
exports my_big_package;
}
[ ] eat a donut from the break room
If you're not married to Eclipse and/or just trying to learn (or are a student with an unhelpful professor/TAs), BlueJ currently has JavaFX already built into it and ready to go, so no extra setup or download is necessary. Neat!
