How to install javafx linux

ubuntu 18.10 — how to install JavaFX with java

I have both openjdk8 and 11 installed. Neither comes with JavaFX. I installed both openjfx and libopenjfx-java packages, but can’t get my app to work.

sudo apt list --installed| grep jfx WARNING: apt does not have a stable CLI interface. Use with caution in scripts. libopenjfx-java/cosmic,cosmic,now 11+26-4 all [installed] libopenjfx-jni/cosmic,now 11+26-4 amd64 [installed,automatic] openjfx-source/cosmic,cosmic,now 11+26-4 all [installed] openjfx/cosmic,now 11+26-4 amd64 [installed] 

dpkg-query -L openjfx /. /usr /usr/share /usr/share/doc /usr/share/doc/openjfx /usr/share/doc/openjfx/TODO.Debian /usr/share/doc/openjfx/changelog.Debian.gz /usr/share/doc/openjfx/copyright /usr/share/openjfx /usr/share/openjfx/lib /usr/share/openjfx/lib/javafx.properties /usr/share/openjfx/lib/javafx.base.jar /usr/share/openjfx/lib/javafx.controls.jar /usr/share/openjfx/lib/javafx.fxml.jar /usr/share/openjfx/lib/javafx.graphics.jar /usr/share/openjfx/lib/javafx.media.jar /usr/share/openjfx/lib/javafx.swing.jar /usr/share/openjfx/lib/javafx.web.jar 

Am I supposed to somewhat copy the libraries to java lib folder? Otherwise it does not compile blabbering not existing javafx.* packages Previously working jar now exits with:

Error: Could not find or load main class helloworld.HelloWorld Caused by: java.lang.NoClassDefFoundError: javafx/application/Application

Installing the JavaFX SDK

The JavaFX Software Development Kit (SDK) provides the command-line tools and technologies to develop expressive content for applications deployed to browsers, desktops, and mobile devices.

The JavaFX SDK runs on Windows and Mac OS X. A beta release of the JavaFX SDK is provided for Ubuntu Linux and the OpenSolaris operating systems.

Contents

System Requirements

The system requirements for the JavaFX SDK, including the recommended version of the Java SE Development Kit (JDK), are listed in the JavaFX System Requirements document.

Installing the JavaFX SDK on Windows or Mac

On Mac OS X, the installation procedure also creates the following directories:

 /Library/Frameworks/JavaFX.framework/Versions/Current /Library/JavaFX/Home /usr/bin/javafx /usr/bin/javafxc /usr/bin/javafxdoc /usr/bin/javafxpackager 

For information about samples and documentation in the SDK, see the README file in the top level of the SDK directory.

Installing the JavaFX SDK on Ubuntu Linux or OpenSolaris

 chmod a+x javafx_sdk-1_2-linux-i586.sh ./javafx_sdk-1_2-linux-i586.sh 

The shell script installs the JavaFX SDK in the current directory.

For information about samples and documentation in the SDK, see the README file in the top level of the SDK directory.

Release: JavaFX 2.2

1 JavaFX Installation for Microsoft Windows

2 JavaFX Installation for Linux

3 JavaFX Installation for Mac OS X

We Welcome Your Comments

If you have questions about JavaFX, please go to the forum.

JavaFX 2.2 Installation Guide

2 JavaFX Installation for Linux

This page provides information about the installation procedures of the JavaFX 2.2 SDK on Linux platforms.

Web Start applications and Web applications (plugin) features are currently not supported on the Linux platform.

Installing JavaFX

The JavaFX 2.2 SDK for Linux is installed as part of JDK 7 update 6 for Linux. See the JDK 7 update 6 platform requirements and installation instructions, see "JDK 7 Installation for Linux" at
http://docs.oracle.com/javase/7/docs/webnotes/install/

If you want to use JavaFX 2.2 on a JDK 6 platform, perform the following:

1. Download the JavaFX 2.2 SDK zip file from http://www.oracle.com/technetwork/java/javafx/downloads/index.html
2. Extract the SDK files from the zip file to a directory on your local file system. Once JavaFX SDK is installed, you should see the following directory structure on your system: javafx-sdk2.2/
   bin/
   docs/
   rt/
   .
   ..

Installing NetBeans IDE

NetBeans IDE 7.2 is recommended for the JavaFX 2.2 SDK. Download the NetBeans IDE from the JavaFX Downloads page.

For information about configuring NetBeans IDE to run with JavaFX, see Setting Up NetBeans IDE With JavaFX at
http://netbeans.org/kb/docs/java/javafx-setup.html

How to install JavaFx in Ubuntu 12.04?

I download JavaFx from here. I placed it in my home directory( anto ) under the name javafx . Then I did something like this :

javaFx_home=/anto/javafx/rt/lib/jfxrt.jar export PATH=$PATH:$javaFx_home

Automatically: (via webupd8 helper ppa repository)

sudo add-apt-repository ppa:webupd8team/java sudo apt-get update sudo apt-get install oracle-java7-installer 

Note: You can replace oracle-java7-installer with oracle-java8-installer or oracle-java9-installer . You will need to accept the Oracle End User License Agreement prior to installation (this isn't required with OpenJDK, so if a OpenJDK back-port is released for 12.04, please update this post! 🙂

Whilst this may theoretically answer the question, it would be preferable to include the essential parts of the answer here, and provide the link for reference.

You can try setting the CLASSPATH instead of PATH . Java tries to load it's classes from the locations referenced by CLASSPATH .

• First check your existing classpath with echo $CLASSPATH . Like PATH , the entries for CLASSPATH are separated with : (colon). The presence of a . entry under CLASSPATH means java can always load classes from current directory.
• To add a .jar library to your CLASSPATH you should open the file ~/.profile and add export CLASSPATH=$CLASSPATH:path to .jar to it. Like in your case it should be

javaFx_home=/home/anto/javafx/rt/lib/jfxrt.jar
export CLASSPATH=$CLASSPATH:$javaFx_home

Here is what I've found so far.

I downloaded JavaFX SDK 1.2 and 2.2 . They have removed some files from JavaFX SDK.

virpara@Ascension:~$ tree -L 2 '/home/virpara/Desktop/javafx-sdk1.2' /home/virpara/Desktop/javafx-sdk1.2 |-- bin | |-- javafx | |-- javafxc | |-- javafxdoc | `-- javafxpackager |-- COPYRIGHT.html |-- docs | |-- api | |-- emulator.html | |-- index.html | |-- javafxc.html | |-- javafxdoc.html | |-- javafx.html | |-- javafxpackager.html | `-- manpage.css |-- emulator | `-- bin |-- invoice.properties |-- lib | |-- desktop | |-- javafx-runtime.properties | |-- mobile | `-- shared |-- LICENSE.txt |-- profiles | |-- desktop.properties | `-- mobile.properties |-- README.html |-- samples | |-- DisplayShelf | |-- DisplayShelfMobile | |-- DragAndDrop | |-- index.html | |-- InterestingPhotos | |-- LocalSearch | |-- MediaBox | |-- PathAnimation | |-- PhotoEffects | |-- PhotoFlip | |-- shared | `-- SpringAnimation |-- servicetag | `-- registration.jar |-- src.zip |-- THIRDPARTYLICENSEREADME.txt `-- timestamp 23 directories, 23 files 

virpara@Ascension:~$ tree -L 2 '/home/virpara/Desktop/javafx-sdk2.2.0-beta' /home/virpara/Desktop/javafx-sdk2.2.0-beta |-- bin | `-- javafxpackager |-- COPYRIGHT.html |-- docs | `-- api |-- lib | |-- ant-javafx.jar | |-- javafx-doclet.jar | `-- javafx-mx.jar |-- README.html |-- rt | |-- COPYRIGHT.html | |-- lib | |-- README.html | `-- THIRDPARTYLICENSEREADME.txt `-- THIRDPARTYLICENSEREADME.txt 6 directories, 10 files 

There is only javafxpackager script in javafx-sdk2.2.0-beta/bin ( javafx, javafxc, javafxdoc scripts are removed) it means that if you export javafx-sdk2.2.0-beta/bin to your PATH variable and try to execute javafx --version in terminal it can't find javafx because there is no executable named javafx .

Well I've no experience with JavaFX but probably they have removed other three scripts because it would not be needed and perhaps javafxpackager would do the thing or java is enough for that.

You've tried to include whole path to jfxrt.jar to PATH variable.

it won't work because it can't automatically pass to -cp parameter. So, you must give full path to jfxrt.jar as -cp /anto/javafx/rt/lib/jfxrt.jar

java -cp /anto/javafx/rt/lib/jfxrt.jar MyProgram.java 

I know it is not a solution.
