B4J Question JavaFX runtime components are missing, and are required to run this application

[hatzisn]

Hi everyone,

I have installed the OpenJDK11+OpenJFX11 from the suggested link in the B4J and B4A product page.
I unzipped it, I updated my paths in B4J and compiled successfully an Application. I exited B4J and tried to run the jar by double clicking on it but I see a black command prompt windows which closes and nothing runs.

I tried with this tutorial to set the JAVA_HOME and I had no success: https://javatutorial.net/set-java-home-windows-10

Testing if it runs the app I see the same (black cmd and closes)

Tried to test the variables and java and here is what I've got.

Spoiler: cmd checking the java environment

C:\Users\Nikos>echo %JAVA_HOME%
C:\B4X\Java\jdk-11.0.1

C:\Users\Nikos>javac -version
javac 11.0.1

C:\Users\Nikos>java -version
Error: opening registry key 'Software\JavaSoft\Java Runtime Environment'

Any suggestions?

Executable jars are not supported by Java 11+.

Best way to distribute your apps is with: https://www.b4x.com/android/forum/t...distribute-standalone-ui-apps.117880/#content

Is this fact (non supported executable jars) valid also for Linux and Mac?

Yes. JavaFX is not integrated in Java 11+ so executable jars will not work. You need to use the packager.

The advantage is that the package doesn't depend on anything (unlike the compiled jar).
