B4J Question How to run JAR from command line in Windows?

[wimpie3]

My app works perfectly in B4J (Windows), in both debug and release mode.

However, I can't seem to run the JAR file outside of B4J.

I'm trying this:

C:\java\jdk-14.0.1\jdk-14.0.1\bin\javac.exe -jar C:\myapp\B4J\Objects\myapp.jar

JDK 14.0.1 is also the JDK I'm using in B4J.

I get this error:

Error: JavaFX runtime components are missing, and are required to run this application

How is it possible the file runs perfectly inside B4J, but not using the command line?

You missing JavaFX in version 14

Use this, It is with JavaFX

Maybe also set the Path so Windows can find your Java.

B4J adds all the required modules.

The simplest way to run the app is by building a standalone package.

Other ways:
1. Compile with Java 8. This will create an executable jar (depends on Java 8 being installed and configured as the default Java).
2. I don't recommend it but if you don't want a standalone package and are running it on a computer with B4J Java then you can follow these instructions: https://www.b4x.com/android/forum/t...les-to-minimize-disk-usage.121642/post-760317

This was already the version I was using. So this is not the correct solution.

Option number 2 worked perfectly, thank you Erel!

Why it is always the option that I don't recommend LOL
