Thank you so much for this video! We've been looking everywhere for help to get our JavaFX going. We really like your teaching style because you so patiently explain everything. You saved from us a world of agony as we worked so hard to not only figure this out, but to find someone who could walk us through it, including the red error on NetBeans that you showed how to get past. What a lifesaver!
Hello! I usually don't comment but I really just wanted to say thank you so much, sir! It was such a relief to finally see my project run after a series of troubleshooting and asking around but not getting any progress either. I am currently a computer science student and your videos help a ton!
Great video. I appreciate the time you took to make it. To avoid retyping all that portion of code needed for every new JavaFXML project I have created a JavaFXML project (the one you have described here would do just fine) and use it as a template for new JavaFXML projects. When I need a new project I just right click on this template project and select the Copy option and use the Refactor option to change the current project name to a new one. Just my 2 cents for you guys.
This is fantastic. I tried using JavaFX years ago and I didn't have a clue and couldn't find much help especially with the errors, but not only has this video shown me how to get the newest (2020) Netbeans set up for JavaFX it's also taken me through the process and helped me understand what is going on. I can't thank you enough for your efforts on this. Cheers.
Glad that you found it useful! It was the culmination of weeks of frustration that my colleagues and I were experiencing. I pieced together parts of the puzzle I found around the Internet and previous experience and just put this together hoping it would save other folks some time. :)
I was failed using Apache netbeans after installing, now I'm enjoying bcz of u! Thanks man, Also I shifted to eclipse installed it then I got the same issue , and decided to take a break for some months now for this am back, plz do the samthing to eclipse I love it so much
This was the VM Option I had to add to get my system to work: "--module-path "C:\Users\samuel\Documents\JavaFX\javafx-sdk-14.0.1\lib" --add-modules=javafx.controls,javafx.fxml"
Whenever I save the changes in SceneBuilder every time I click the .fxml file in netbeans it pulls up Scene Builder again and not the raw fxml code in NetBeans. Any fixes/suggestions?
Go under Tools --> Options --> Java, then under the JavaFX tab, you can select the home directory of Scene Builder (that's the folder it's installed in) - this should change that behavior.
hi There i am trying to convert my project in exe mode but facing a error Unable to create javax script engine for javascript in Javafx application can you please help me . i tried online coundnt get proper solution . Please help thank u
Great video. I've followed every step and everything seems to be ok, no syntax errors. But when I run the program I get this annoying message "exception in application start up method". Do you have a remedy for that. Thanks anyway.
in the java plattform manager i have jdk 13 and its selected as default, but when i want to create a javafx project i only can choose between java 1.7 and java 1.8. Because of that i get allways an error(52) if i want to start a created javafx app. how can i get from 1.8 to jdk 13?
thank my error was that when running my project javafx13 and jdk13 it was showing in execution but not showing the gui javafx i am resolving with adding to the method main of the class that calls Scene "launch(args)"
Hi John ! Nice video, many thanks sharing your knowledge ! But how could i add the JAVAFX Javadoc on netbeans ? I am tired using external browser and it took me hours searching the web for a solutions, but i only found a few bug reports with no solution to fix it. And you also did not show how to activate the Javadoc in this video. Do you have an solution on hand for Netbeans ? I finally switched to IntelliJ, here i was able to activate the Javadoc for FX, but i am really missing the easy "Make Controller" functionality, its not implemented in IntelliJ :-/ Greetings Timo
It's rare people like John who selflessly contribute so much to software development. I hope that you get some reward from the many positive comments. Respect and thank you.
The part where I do the "faking out" NetBeans - you act like you're going to create a JavaFX project through Apache NetBeans, and then it will "activate JavaFX", and then you cancel. Then, you go back and create a regular Java app and add the JavaFX libraries.
They are improving the software, so hopefully it is / will quickly become super easy to use the open source OpenJDKs soon enough. I haven't explored it much lately, but I suspect it's definitely better than when I created this video. I'll hopefully be checking it out again soon. :)
John, first of all many thanks for contributing your excellence - it clearly has helped many coders such as me. I have a NetBeans problem and I'm hoping that you can shed some light. I have installed the latest version plus Java V14 libraries, and got the HelloFX demo working. Now I want to run this on a Raspberry Pi (running Debian) on which I have installed what I believe to be the most up-to-date Open libraries (jdk & jfx). When I create a Java Platform for the Pi, it tests fine. But when I try to point the project's Run at it, the new platform simply does not show in the Platform dropdown. Any ideas ?
Let me understand correctly - where do you have Apache NetBeans installed? On your (Windows?) PC? Or on the Raspberry Pi? What do you mean by, "... try to point the project's Run at it..."? What is "it"? The Apache NetBeans' Run options doesn't list something? The project you're working on, etc.?
@@profjpbaugh NetBeans is installed on my laptop, running Windows 10. I have your example project "HelloFX" running on it. Locally it runs fine. I have set up a Java Platform "pi" in NetBeans pointing to the remote Raspberry Pi machine (ie. IP, login credentials,...). I want to run the same JFX program on there. In the Project Properties Run category I try to specify the Runtime Platform as "pi" but that simply does not appear in the dropdown. Four years ago I did a fairly major development using these platforms. I developed remotely using NetBeans and deploy to the pi. Recently I have taken this up again for a different project but it seems that a lot of water has passed under the bridge since then !
John - It would appear that your (excellent) project setup "localises" NB. That is, the setup may preclude a remote connection. The reason I say this is that before running your setup from scratch (ie. fresh install of V12), with NB V11 I did get a small Java app working remotely on the Pi. In addition, I have two differently-configured Pi's - I have tried both. I have set up remote platforms for both, and both test OK. I believe NB does a 'probe' on the remote platform - this seems to work fine as there is no error message. I have logged a support ticket with Apache. I just wish I could find some statement which explains why NB will pre-filter a project's Runtime Platform dropdown.
John. I have got a bit further. In Project Properties -> Sources -> Source/binary format dropdown, if I change this to JDK11 then my Java platforms now appear in the dropdown in the Run category ! Still doesn't work, but NB deploys to the Pi and tries to fire up the jar file. Bit further.
Got there. 1. The JDK version MUST match up with the version installed on the Raspberry pi. 2. The X Server must be running, and the DISPLAY environment variable declared (DISPLAY=:0). Other than all that, piece of cake ! Jim
Hi, may I ask is there a plugin for javafx13 and apache netbeans 11.2 for printing invoice? Cause I cant install IReport and JasperReport. Please help me. Thank you!
A way to fix the error that when trying to enter javafx in the current netbeans once and for all and without doing these maneuvers is quite simple. You have to download these 3 programs: Current Apache Netbeans - Java kit jdk version 8 w / netbeans (this version already comes with netbeans + JAVAFX embedded in it) -scenebuilder. First install the JDK normally. then you install Apache netbeans (yes you will have both versions of netbeans, a new and old), at the time of installation it will recognize the JDK 1.8 folder (which already has the embedded javafx) and do the installation normally. Then scenebuilder is installed. Open apache netbeans and you will see that the error in javafx will no longer occur. From Brazil. Enjoy.
Yes, if someone wishes to use the Oracle version of the JDK, then it is now straightforward. But, if you create commercial software, Oracle can sue you if you don't pay their monthly fee. It's not particularly expensive, but it's more the principle that Java has been free for almost 30 years, and now Oracle has decided to monetize it.
If you're not getting the "Make controller" option, it is likely that you didn't follow the step related to "Creating a JavaFX project". It's the part of the video that I refer to "faking NetBeans out" - you start like you're going to create a JavaFX project using the Apache NetBeans project options, but then you cancel once it's done "Activating JavaFX". The part where you "activate JavaFX" is what seems to allow you to pick to "create controller". See if this fixes your issue. Also, just so I'm clear - you're using Apache NetBeans, correct? Which version? 11.2? 11.3?
The way I've found around this, is you "pretend" you're going to make a JavaFX application through Apache NetBeans itself (using their techniques), and when it activates JavaFX, you then just back out and use my techniques to ensure the open JDK is used, and you will see the Controller option among other things (like FXML files being an option for file types).
Hey man, I am the same guy as before but I have an issue which is driving me crazy. I can't fix it for some reason. For the past few weeks I have been working with javafx on netbeans like you do and I even made a working calculator. Our teacher asked us to make a java with maven project. I tried it. Couldn't figure it out and I went back to java with ant. But now I get a major error. "Cannon access java.lang" ,"Unable to find package java.lang in classpath or bootclasspath". I tried un-installing the program and installing it back, I tried going to ...../netbeans/etc and changing the netbeans conf file homepath to the java one, to the sdk one but all of them failed. Every project that worked now doesn't for some reason. If you could help me out it would mean the world to me since I have a project for university that I need to do. Thank you!
Since java.lang is the primary package (which is included implicitly when you create a Java program), my suspicion is you somehow removed the reference to the JDK itself. Or, maybe you're using an incompatible version of the JDK? When you right click the project and go to the properties, what version of Java is it using? If you're using the netbeans.conf file, are you sure the JDK and NetBeans are on the same drive? I found some squirrely behavior at one point related to that. Are you on Windows?
@@profjpbaugh thank you man for your reply! I am using Netbeans 12.5 ( for the university project, they ask for that specific version ) and I am using JDK 18. I am on windows 10 and that's the conf path "netbeans_jdkhome="C:\Program Files\Java\jdk-18.0.1"". Like I said the program was running fine until I tried java with maven, that screw everything up
@@basilhsxatzhkostas Couple questions: 1.) Are regular Java Applications (e.g., "Hello world!" console app) using Ant failing also, or just JavaFX? 2.) So you created an Ant project and used JavaFX, and it worked, THEN you tried using Maven with JavaFX, and it failed, and now you switched back to Ant, and it's failing? I'm just trying to understand the problem better.
@@profjpbaugh You understood correctly. Everything you said on 2 is correct. As far 1 is concerned yeah it's failing on the simpliest app. btw I went to a friend's house a few hours ago and finished the project since I wasn't able to fix the issue. Thank you tho man so much for your help. Really appreciate it!
@@basilhsxatzhkostas As a sanity check, make sure your JDK is actually located where you told it (in the config file). Maybe set an environment variable JAVA_HOME to the location of the JDK and then re-launch NetBeans. (If you're unfamiliar with setting environment variables, you just search for "environment variables" using the Windows search near Start and then Edit Environment Variables. Add it as a system variable. So, the name of the variable would be JAVA_HOME, and C:\... or wherever the location of your JDK is, would be the value. I'm wondering if it's using the config file or maybe the environment variable is overriding it.
John, first of all, congratullations for this explanation. It really helped me. Now, after following successfully the steps and created my helloFX project, I've created my distribution file clicking on the "Clean and build the project". It created a *.jar file, but when I double click on it, nothing happens. Do you have any clue to me? I have installed the JRE Version 8 Update 241 on Windows10
yeah my application runs pretty smooth with no errors or warnings in IDE but i am unable to run directly or from cmd. Can you run the application from cmd and see what error you get? i get "JavaFX run time components are missing and they are required to run this application" if you find any fix let me know as well i'd appreciate it
Where is the default Java (java and javac) directory, such as JAVA_HOME in the environment variables? Is it in a Java 8 installation? Or do you have the JAVA_HOME set to Java 13 or 14, etc.? There is a java.exe under wherever you install the JDK 13 or 14, etc. Have you tried it with that?
@@profjpbaugh i set up my default JAVA_HOME directory in environment variables pointing towards java 13 or 14. But still the jar file in my distribution folder wont work. Its been a week now im implementing the same project in C#. Are you able run your javafx project from distribution folder? If yes then maybe we are doing sth wrong. But they have made things too much complicated since java 8.
@@profjpbaugh it was not doing anything at all but then i ran the program through cmd and there was an error which said "javafx run time components are missing and are required to run this application". Several people got this error when they were running their program in IDE and they have forgot to set module path and VM options but for me module path and VM options are already configured and i have included all the dependent libraries and i have no issue in running the application inside the IDE. On Openjfx website they have already addressed this error. To fix this error you either have to add javafx.graphics on module path or you have to set another main class for project which does not extends javafx.application.Application. Here is the link if you wanna see that error yourself: openjfx.io/openjfx-docs/ Even after the configuration of a dummy project(which has just "click me" button) wont work outside the IDE and it will run absolutely fine inside IDE. Same thing goes for my actual project.
It is an auto-complete option / shortcut that is built in to Apache NetBeans. You type psvm and hit tab and it autogenerates the skeleton of the main method.
@@PrivatMann I'm not sure I understand your question. The psvm stands for public, static, void, main. But it's like autocorrect in say, Microsoft Word. E.g., if you type "teh" it automatically changes to "the". Similarly in Apache NetBeans, if you type "psvm", it changes to the full return type, signature and empty body of the Java application entry point, the main method.
@@PrivatMann I'm still not sure what you are asking. You type the letters "psvm" and then press the Tab key and it fills in the main method skeleton. This is automatically set in all versions of Apache NetBeans that I have used. :)
Great video. I've followed every step and everything seems to be ok, no syntax errors. But when I run the program I get this annoying message "exception in application start up method". Do you have a remedy for that. Thanks anyway.

(If you're unfamiliar with setting environment variables, you just search for "environment variables" using the Windows search near Start and then Edit Environment Variables. Add it as a system variable. So, the name of the variable would be JAVA_HOME, and C:\... or wherever the location of your JDK is, would be the value.
I'm wondering if it's using the config file or maybe the environment variable is overriding it.
John, first of all, congratullations for this explanation. It really helped me.
Now, after following successfully the steps and created my helloFX project, I've created my distribution file clicking on the "Clean and build the project". It created a *.jar file, but when I double click on it, nothing happens. Do you have any clue to me? I have installed the JRE Version 8 Update 241 on Windows10
yeah my application runs pretty smooth with no errors or warnings in IDE but i am unable to run directly or from cmd. Can you run the application from cmd and see what error you get? i get "JavaFX run time components are missing and they are required to run this application"
if you find any fix let me know as well i'd appreciate it
Where is the default Java (java and javac) directory, such as JAVA_HOME in the environment variables? Is it in a Java 8 installation? Or do you have the JAVA_HOME set to Java 13 or 14, etc.?
There is a java.exe under wherever you install the JDK 13 or 14, etc. Have you tried it with that?
@@profjpbaugh i set up my default JAVA_HOME directory in environment variables pointing towards java 13 or 14. But still the jar file in my distribution folder wont work. Its been a week now im implementing the same project in C#.
Are you able run your javafx project from distribution folder? If yes then maybe we are doing sth wrong. But they have made things too much complicated since java 8.
@@muzamilmehmood1398 Is there a specific error either of you are getting when you double-click the jar file? Or is it just not doing anything at all?
@@profjpbaugh it was not doing anything at all but then i ran the program through cmd and there was an error which said "javafx run time components are missing and are required to run this application". Several people got this error when they were running their program in IDE and they have forgot to set module path and VM options but for me module path and VM options are already configured and i have included all the dependent libraries and i have no issue in running the application inside the IDE. On Openjfx website they have already addressed this error. To fix this error you either have to add javafx.graphics on module path or you have to set another main class for project which does not extends javafx.application.Application. Here is the link if you wanna see that error yourself:
openjfx.io/openjfx-docs/
Even after the configuration of a dummy project(which has just "click me" button) wont work outside the IDE and it will run absolutely fine inside IDE. Same thing goes for my actual project.
Спасибо.
Спасибо большое, Джон! Теперь у меня всё работает.
It works if you specify in the options like this:
--add-modules = javafx.controls, javafx.fxml
Пожалуйста
Thank you!
Thanks a lot
i will like to learn more from you
how comes you type "psvm" and "public static void main" pops out?
It is an auto-complete option / shortcut that is built in to Apache NetBeans. You type psvm and hit tab and it autogenerates the skeleton of the main method.
@@profjpbaugh what key is that?
@@PrivatMann I'm not sure I understand your question. The psvm stands for public, static, void, main. But it's like autocorrect in say, Microsoft Word. E.g., if you type "teh" it automatically changes to "the". Similarly in Apache NetBeans, if you type "psvm", it changes to the full return type, signature and empty body of the Java application entry point, the main method.
@@profjpbaugh okay. But it don't changes nothing automatically. Maybe false configuration?
@@PrivatMann I'm still not sure what you are asking. You type the letters "psvm" and then press the Tab key and it fills in the main method skeleton. This is automatically set in all versions of Apache NetBeans that I have used. :)
someone know how to make it executable, plis
Make what executable? You can make a .jar file - is this what you are referring to?
Pretty pretty good tutorial,deserve a like and subscribe from me, Hope you continue to help other novice coder like me
thank you شكرا

Great video. I've followed every step and everything seems to be ok, no syntax errors. But when I run the program I get this annoying message "exception in application start up method". Do you have a remedy for that. Thanks anyway.
What is the Exception you are receiving? A little more information might help out. :)
@@profjpbaugh I get "exception in application start method".
