My system is headless so I first use PuTTY to SSH into it and use an X server (vcXsrv) to display the FileBot GUI.

I have installed javafx-sdk-11.0.2 from openjfx,io

When I click on "Load" (either Select Folder or Select Files), I receive the following error:

Code: Select all

However, under 'Select Folder' the only buttons that work are the 'Open' and 'Cancel' buttons; I am otherwise unable to use it.

Under 'Select Files' everything appears to work and this has been my workaround to the above problem.

But I would like 'Select Folder' to work. Any ideas?

Thanks!

You have multiple options.


A.
Install a JDK that includes the JavaFX modules:
https://bell-sw.com/pages/liberica-rele ... es-15.0.1/


B.
Install OpenJRE and OpenJFX and set --module-path via JAVA_OPTS accordingly so that java can find the modules, wherever they may be on your machine.


C.
If you're using Fedora Core, then the Fedora repository might work better for you:
https://www.filebot.net/linux/yum.html


D.
Configure FileBot to not use the GTK native FileDialog:

Code: Select all

filebot -script fn:properties --def net.filebot.UserFiles.fileChooser=Swing

viewtopic.php?t=3913


E.
Ignore the problem and use Drag-and-Drop instead.

This is fantastic help. Thank you very much!

Let us know what worked best for you.

[PriamX]

Well, I didn't go with option E

Option D worked well, but I was less enthused about the Swing-type interface.

I attempted option B because JRE and FX were already installed, but I couldn't get it to work, I'm not sure if it wasn't finding the module or what was going on there; I didn't monkey with it too long.

I finally landed on option A which just worked without issue and gave me the nicer JavaFX file selection interface.

Thanks again for your help.

Just follow-up a couple years later, for those that may come here.

I'm still using FileBot quite successfully on Fedora (now on release 37).

My opinion has changed since solving it with Option A originally, my current opinion is that rednoah's Option C (using the Fedora repository), is far easier to manage; java is hassle-free and Fedora's dnf takes care of the updates and upgrades for you.

Notably, JavaFX is no longer required, since newer version of FileBot use the zenity command-line tool by default if available.


You can force this implementation like so:

Code: Select all

filebot -script fn:properties --def net.filebot.UserFiles.fileChooser=Zenity
