B4J Question Compile Error b4j ver 10.2

You are using Java without JavaFX. Download Java 19 from here: https://www.b4x.com/b4j.html

I get now :

You probably need to add #JavaCompilerPath 24, path/to/java24.0.1

You get this
Java Version: 8
...
javac 24.0.1

if you dont.

Show your IDE Paths Configuration. how do you configure the javac.exe path

What is that running standalone dont work? did you build standalone a package? if yes, you can run_debug.bat to see what reason it does'nt work.
The runtime is included in standalone package, it will not depandent on client java runtime.

The jar files dont work. The standalone package works, but it´s 66MB and several directories. If I have 7 jar files, and I have 7 times this standalone structure ?
And what is with security updates? Normally there is an automatic java runtime updater on the pc of the clients.
With the standalone page I have to update every jar file and do this manually ?

Next problem is I must change all *.jar to *.exe , at the customer side and I dont think yet about the new firewall and virus scanner problems.

I think there must be a reason why my jar file dont work.

I used now a javac.exe from the oracle JDK 1.8 and the jar file also works now with jre441
There is now the problem with fx is not anymore part of the runtime/JDK.
Is there a solution ? Because the updates are coming automatically and fixing security issues.
