B4J Question (NOT SOLVE) Jar files don't run on ARMbian (Pi Board)

[Tayfur]

I use new orangePI borad .
I insatalled ARMbian (Debian Jessei based)
I installed Java SE Development Kit 8u121
http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html

Linux ARM 32 Hard Float ABI : jdk-8u121-linux-arm32-vfp-hflt.tar.gz
installed.

Finally my B4J appalication tested. ==>>" sudo java -jar test2.jar "
Result is "JavaFx runtime companents ase missing"
B4J use same JAva version on PC. (jdk vers 1.8.0_121)

How is fix it ?

Are you running an UI B4J app ?

 

[EnriqueGonzalez]

OpenJDK does not contain javafx natively, if you want to install it you will need:
sudo apt-get install openjfx

Or, you can install Oracle java jdk for javafx too. Instruccions:

That, being said, you should know that running javafx on a arm device may not be the best.

Yes my app has iu (forms/ buton / listbox etc.) therefore, I need to Javafx

I installed Oracle Java8 latest version
for java version see my picture in first line.

After tested my code.

 

[EnriqueGonzalez]

it seems that Oracle killed javafx for ARM devices.

i do not know if openjdk still has it.

this is bad news.

do you have alternatives for ui applicaiton on ARM board.

See the first sentence in the tutorial: https://www.b4x.com/android/forum/threads/b4j-and-raspberry-pi-boards.37019/

Finally my B4J appalication tested

If you don't need to display an interface, just installing:

sudo apt-get update
sudo apt-get install default-jre
reboot

works for non-ui apps

[edit] I previously followed these instructions on Raspbian and it worked :

Yes a webapp

As pointed by EREL, and given the same answer in many similar posts, UI apps are not longer supported by Raspi.... The next best thing is to create a webapp, ABMaterial makes an excellent candidate for this...
