Erro: Não foi possível localizar nem carregar a classe principal javafxapplication01.JavaPuzzleBall

    That is really strange.  Let me investigate.  In the meantime, I have heard of incidences where the game won't run on OpenJDK, but will run on OracleJDK.

    Thanks.

    Maybe it is the point.

    I also installed Oracle JDK.

    I will keep trying.

    I'm able to get the game to work on Java 10.  Is your system using the runtime environment that comes with the Oracle JDK?  I don't believe OpenJDK includes a corresponding JavaFX implementation (OpenJFX) by default, which means you'd have to install additional packages to get the game to work using OpenJDK.

    I'm also on 18.04, and the game doesn't run for me on openjdk 10. This is what I did:-

    sudo apt install openjdk-8-jdk openjfx

    sudo update-alternatives --config java

    From this menu, choose Java version 8 and then you should be able to run with:-

    java -jar JavaPuzzleBall.jar

    I seem to be having the same problem running the Jar:

    java -version

    openjdk version "1.8.0_131"

    OpenJDK Runtime Environment (Zulu 8.21.0.1-macosx) (build 1.8.0_131-b11)

    OpenJDK 64-Bit Server VM (Zulu 8.21.0.1-macosx) (build 25.131-b11, mixed mode)

    java -jar JavaPuzzleBall.jar

    Error: Could not find or load main class javafxapplication01.JavaPuzzleBall

    Any ideas ?

    Hi Lee,

    The culprit is OpenJDK.  OpenJDK doesn't include a JavaFX counterpart by default.  One option is to install additional OpenJFX packages to make up the difference.  Or another option is to install and run the game with Oracle's JRE.

    the above example is in Windows 10.

    While ago I tried it in Virtual Box - Oracle DB Developer VM, and it works ( but it is slower ).

    I would appreciate to make in run on Win10 as well, but it is not urgent.

    Thank you.

    Libor.

    That's a new one.  I'll have to see if I can reproduce it.  Is anyone else having trouble on Windows 10?
