B4J-Bridge is very useful for programming the Raspberry Pi (see this tutorial): https://www.b4x.com/android/forum/threads/jpi4j-raspberry-pi-gpio-controller.37493/

Note that starting from Java 8 it is no longer possible to create UI apps that run on these boards. If you need to create an interface then you can create a web app together with the local browser.

As far as i know, JavaFX exists in the first versions of Java 8. Oracle removed it in Version 8.33.
Therefore you should avoid updating Java.

Correct- 8u6 is the latest recommended on the Pi with JavaFX support.

Installing OpenFx solves the problem with latest JDK (which does not include JavaFx).

Does it means that we can run ui apps on our raspberry pi? (Without any limitations)

Is it possible to create a webapp via b4j?

Yes. Note that you are not posting in the correct place.
