Platforms

You must build the package on the target platform.
Windows - Java 11 should already be installed. Note that Java 11 is 64 bit only.

OpenJDK 11 + OpenJFX 11 (SDK + jmods) - GPL + classpath exception license
Mac - https://b4xfiles-4c17.kxcdn.com/b4j/mac_jdk-11.0.1.zip
Linux - https://b4xfiles-4c17.kxcdn.com/b4j/linux_jdk-11.0.1.zip
Referring to the tutorial https://www.b4x.com/android/forum/t...the-simplest-way-to-distribute-ui-apps.99835/

I am confused with the steps explained above.

Where should I extract linux_jdk-11.0.1.zip to?
Answer: I extracted to /home/{user}/jdk-11.0.1

How do I build the package on the target platform?
Answer:
1. Build Release app from B4J IDE in Windows.

2. Copy B4JApp.jar file from Objects folder to Linux /home.

3. Copy B4JPackager11.jar to Linux /home.

4. Create packager.json in Linux /home
B4X:
{
  InputJar: "/home/com/B4JApp.jar",
  IncludedModules: ["jdk.crypto.ec"]
}
*Note: com is my username in Linux

5. Run the following command in Linux:
B4X:
/home/com/jdk-11.0.1/bin/java -jar B4JPackager11.jar packager.json

6. The package is created in /home/com/temp/build

A video tutorial may be much helpful. Thanks.

this 2 will give you an insight

compile in linux:

compile in mac:

TL:DR, download java as you may do usually in linux and connect the IDE with b4j bridge.

The java openjdk 11.0.8 is missing JavaFX.

I extracted the openjdk 11.0.1 and call java -jar but error show Java not found.

I am using the latest Ubuntu 20.04.1 LTS desktop.

I tried to merge both files, it seems to work. I think this is not a proper way.

I am not sure why when I click on the .sh or run.command in Ubuntu 20.04, it opens TextEditor and doesn't execute the script. When I run using terminal (sometimes with sudo), the script runs.
I found the solution.

Click the hamburger menu and select Preferences. Go to Behavior tab, under Executable Text Files, select Run them.

Thanks for clear instructions. Used your info to build my apps on LinuxMint 18.2 on my Laptop.
Can copy the build to a USB with a linux format and then copy to other Linux distributions. Works a treat!!!
