Strumenti / Configura Percorsi = C:\Program Files\Java\jdk-11.0.1\bin\javac.exe
Java11+FxRuntime downloaded from B4x.com web site

B4X: 
C:\Windows\System32>java -version 
java version "1.8.0_261"
Java(TM) SE Runtime Environment (build 1.8.0_261-b12)
Java HotSpot(TM) 64-Bit Server VM (build 25.261-b12, mixed mode)

When i try to start a jar with
c:\program\java\jdk-11-0.1\bin\java.exe -jar c:\test\test.jar

this error appear: "Error: JavaFx runtime components are missing, and ae required to run this application"

Also using integrated Packager11 the .exe not start correctly

What is the reason of above error, and how to correct?

Not sure you can use Packager11 for Java 8 ( I may be wrong )

Sorry just noticed it was Windows reporting the version not the IDE.

Looks like you have both Java 8 and Java 11 on your computer. Did you compile your program with 8 or 11 ? Make sure that the path to javac.exe points to the correct exe file (i.e. for Java11)

[edit]
Sorry "Strumenti / Configura Percorsi = Configure paths"] Need to brush up on my Italian ?

Did you download Java11+Fx from Erel's link or elsewhere on the forum?

Try it with
B4X: 
c:\program\java\jdk-11-0.1\bin\java.exe -version
to define the java you want to check.
Windows is finding an old version as you do have two javas installed. Maybe javahome set as env var?

No, I don't have any environment variables with the name JAVA_HOME
But shouldn't the version configured on Tools / Configure Paths be used?

If i try to use c:\program\java\jdk-1.8.0-261\bin\javac.exe on "Tools/Configure Path", the .jar produced run fine with
c:\program\java\jdk-1.8.0-261\bin\java.exe -jar c:\test\test.jar
But integrated packager is not available
May be that some library are not compatible with java 11 ?

Yes, B4X IS using the configured java!!

YOU are running the command from a windows commandline. WINDOWS is deciding which to use if you do not specify a path!

The integrated packager does need Java 11 as far as i know..

B4JPackager11 is a utility written in B4J that uses the underlying Java tools to create a standalone package that doesn't depend on any other software being installed.
It works with OpenJDK 11 and OpenJDK 14.

I now remember .... I had the same problem. You HAVE to include the path to JavaFX and the required modules in the command line. Tried it on my computer:

C:\java\jdk-11.0.1\bin\java.exe --module-path C:\java\jdk-11.0.1\javafx\lib --add-modules=javafx.controls,javafx.fxml,javafx.web -jar PATH-TO-YOUR-JARFILE

Change the paths above for your setup.

In general, the command line is:

%JAVADIR%\bin\java.exe --module-path %JAVADIR%\javafx\lib --add-modules=javafx.controls,javafx.fxml,javafx.web -jar %JARFILE%

No
"..When i try to start a jar with c:\program\java\jdk-11-0.1\bin\java.exe -jar c:\test\test.jar ...."

Then Windows cannot decide wich Java version to start

Yes, It could be that java.exe takes it from the imposed path while other libraries from other directories
I also tried the system you recommended but I get another error
Any idea?

Most likely, the EXE created had the same issue as post # 11. The problem is that this thread started going off track by trying to start the .jar file manually with Java 11, with Java 11 really not supporting running UI applications in a straightforward way as was available with Java 8. Quote from @Erel: "Java 11 doesn't support executable jars (for UI apps). You need to use B4JPackager11 to create an package with an embedded Java" (source: https://www.b4x.com/android/forum/t...ava-11-cannot-run-jar-file.105016/post-658007). You should probably have run the run_debug.bat batch file and used the error output from that to post your error that you were experiencing with your original issue (Java 11 EXE not executing properly).

Run the Command Prompt as Administrator.

Make sure that your paths are correct. Also see the link below. It make it much easier to run a Java11 jar file from the command line when you define the paths as environment variables and create a BAT file. Run the BAT file as Administrator.

How to execute JAR file with JAVA 11? (JavaFX Components missing)

If you used to execute jar files in command line this way before: java -jar MyProgram.jar Or double-clicking on the JAR file, you will probably end up having this error showing up: Error: JavaFX runtime components are missing, and are required to run this application ... so here is the fix...

You (plural) realize that the packager created a batch file already that runs the app from the command line? It’s called run_debug.bat

Did not know that.
However to run the JAR file from the command line, you don't need to run the packager. Just compile the JAR and run it as specified in my previous post. Works like a charm for me. I have both the Java8 and Java11 JDK installed and compile for one or the other using the #JavaCompilerPath attribute. Then run it for testing purposes directly from the CMD line.

If you're super lazy like myself, then you have a batch file figure out which Java version to use to run a particular .jar file. See: https://www.b4x.com/android/forum/t...8-or-11-via-batchfile-windows.106431/#content . Note: You may need to adapt it to handle cases such as encountered in post #11 of this thread.
