B4J Question Unable to execute the b4j created .jar using Java - reg.

[beelze69]

Hi,
I am a newbie to B4J.
I created a sample test application (I have attached the program here).
I ran the application and it ran perfectly from the IDE.
It created a file prjTest.jar

However when I execute java -jar prjTest.jar it gives error.

Please help.

Thanks

What Java version are you trying to use?

Running jars under OpenJDK 11

With Java 8 you could run a jar on a Windows PC by double clicking on it. This does not work with OpenJDK so as I want to be able to quickly run some utility B4J programs easily without packaging them this is what I did. 1) I installed OpenJDK in a convenient place, mine is in 'C:\jdk-11', and...

Hi Agraham,

It is 1.8.0_291

Attached the screenshot output of java -version command...

And what is the full error you got when running it?

Hi Don,

Attaching the screenshot of the full error message...

 

[DonManfred]

sounds like you are using jar(s) which are compiled for a newer java version.

The simplest configuration is OpenJDK 11: https://www.b4x.com/b4j.html and build a standalone package.

tools->configure paths: javac.exe is from the java version 1.8.291? just guess maybe you installed 2 versions of java and only 291 is in Windows path.

Sorry Erel for late response ... (I was busy with some other activity)...

Yes..You standalone package works perfectly fine (I am able to execute the .exe file created) .. but I want to execute the created jar file ...

I am attaching the error message that says .. it requires JavaFX runtime components...

How should I go about further ?

Thanks...

You will need to use Java 8 instead of 11 if you want to run the jar directly.
