You did compile the app in RELEASE Mode?

In my opinion, packer has a problem with websocket 'ws' packages.

If so, what can I do to run an ABM server app in production? only using IDE in release mode? I hope there is a better way...

I just take Java in a zip from B4X. I unpack to disk and do .bat to start the .jar server.

...but for what I know this is possible only using Java jdk 8. Using (as suggested) OpenJdk 11 the .jar is not runnable....or not? Really can I run the .jar in a OpenJdk environment?

Once it was mandatory the use of Java Jdk. When more or less one year ago in the ide was integrated the packager it was necessary to use OpenJdk to generate a .exe (instead of Launch4j. But using this environment the .jar cannot be launched...or there is a trick to launch it?

Ok I did a quick check.
Websocket does not work in the 'Build standalone Package'. You will not make an ABMaterial server into an 'exe'.
The only thing you have to do is to download from B4X Java11jdk or 14 in zip. Unzip it somewhere on your hard drive, then in another directory you upload your jar server in ABMaterial: jar, www, js,css,font and the necessary files as you had in the project.
Change start.bat for your project and run it. It works 100%.
You can remove all directory 'javafx' from JDK, it is not needed for server.

start.bat:

set JAVADIR="C:\b4x\jdk-14.0.1"
set JARFILE="c:\projekty\testy\ab3\B4J\Objects\ab3.jar"
set STARTDIR="c:\projekty\testy\ab3\B4J\Objects\"

cd %STARTDIR%
%JAVADIR%\bin\java.exe --module-path %JAVADIR%\javafx\lib  -jar %JARFILE%

PAUSE

This only applies to UI apps ? You can run nonui apps with java -jar

Of course you can run no-ui applications, but the point is that B4J Packager builds the 'exe' application so that the websockets from ABMaterial do not work well.
