JavaFX runtime components are missing

English Applications
#1

Hi All,

Leap-42.3 on Gnome Desktop.
Trying to run a java file gave the following error. I am completely clueless about JAVA.
Would welcome guidance to overcome this issue. I have the OpenJDK 8 runtime environment installed along with other related components.
A search on the web has not revealed any software for Leap 42.3. Although ‘one-instal’ suse software for Leap-15 is available.

rsp> ./ITR.sh
Error: JavaFX runtime components are missing, and are required to run this application

Would be obliged for help.

Regards,

Leap-42.3 on Gnome Desktop

This is not a supported Version any more, and openjfx does not build on it…

So install a supported Version and you will get openjfx:
https://build.opensuse.org/package/show/home:Sauerland/java-1_8_0-openjfx

This is a Branch from /home/Herbster0815

You might want want to use the latest and greatest java: https://openjdk.java.net/projects/jdk/12/ plus: https://openjfx.io/ You need to specify --module-path <your module dir> --add-modules <module1,module2…> see: http://jalbum.net/forum/message.jspa?messageID=334117#334117

JavaFX is part of the Oracle Java JDK.
The openJDK equivalent of the JDK is the “devel” package, ie openjdk-devel.

Not that long ago, there was a thread that claimed that JavaFX was missing from that package, too but is highly doubtful.
Install and if you find it missing or have issues, post again.

I have installed:

There is no javafx in any of these packages which is annoying. I reported, but there is no action. I doubt there will be any action in the near future: https://bugzilla.opensuse.org/show_bug.cgi?id=1135525

Then,
This is the main project page
https://wiki.openjdk.java.net/display/OpenJFX/Main

And this page links to downloads
Runtime
https://gluonhq.com/products/javafx/

I haven’t used any of this, so YMMV
Development
https://github.com/javafxports/openjdk-jfx

This project started off separate from the main openJDK-devel, then integrated. Maybe they split off again.

Hi** Sauerland,

Thanks a lot for your quick reply. I got the desired package from the URL you sent. It has worked. Upgrading to Leap-15 is due but I am avoiding it because of the hastle of resetting my desktop.

Thanks & Regards,
