Issues with JavaFX when running pdfsam

I just installed pdfsam along with the javafx and java-9 dependencies. However as soon as pdfsam tries to draw its window the program crashes. From the stacktrace it looks like javafx just isn't linked right but I don't know enough about how java works to link it

I've set my env so I know it's using the right java
   

JAVA_HOME=/usr/lib/jvm/java-9-openjdk

And here's the stacktrace

Exception in thread "main" java.lang.NoClassDefFoundError: javafx/scene/layout/HBox

Re: Issues with JavaFX when running pdfsam

You usually don't have to set your env manually, and that might be the problem, just set the correct environment using archlinux-java FWIW depending on what the program depends on  you might be better off with openjdk 8 in general, since 9 did contain some changes that might render certain programs unbootable. I'm not entirely sure if java 9 would need it's own openjfx package or if it can use the libraries from the java 8 release.

If your end goal is to simply run the program using java 8 will avoid a few potential gotchas anyway.

Hi ripread, there's also the Wiki option if you want to keep your default environment java9, although may have to be aware of it if/when pdfsam updates to java9. I put the script in /usr/bin, called it "pdfsam_run" and then changed the pdfsam launcher in /usr/share/applications to it.

Re: Issues with JavaFX when running pdfsam

FWIW for java 9 we indeed do not have the openjfx libraries currently: https://bugs.archlinux.org/task/55776
