Yes. I have the requirements satisfied.

OS: Windows 11 (updated to the latest version)

JRE: 1.8 (tried re-installing and re-updating)

JDK: 19 (tried re-installing and re-updating)

Other things I tried:

- Running the jar file via Windows GUI (I followed the instructions to set the default app in control panel, etc.). The app suddenly closes when clicked.

- Running the  jar file via command line.  I tried different java executables from both C:\Program Files\Java\jdk-19\bin and C:\Program Files\Java\jre-1.8\bin such as javaw.exe, javaws.exe, java.exe (and all .exe) but no luck.

The traceback is as follow:

java -jar .\vdpplayground.jar
Exception in thread "main" java.lang.NoClassDefFoundError: org/json/JSONException

... 4 more

Are there other requirements needed for this to be ran in Windows 11? .e.g. additional pre-requisite software, or deprecated jar files that needed to be downloaded?

Thanks!

Hi @sed,

Please try downloading VDC Playground on another machine to see if it works and share your result with us. Make sure you have the required jar in your CLASSPATH. 

Here are some things you can try to resolve the issue:

1. To start, try finding out the jar file that's causing the problematic class file.
2. You'll need to check whether your classpath contains that jar, if your classpath doesn't contain the jar then you'll need to add that class in your classpath.
3. If the jar is present in your classpath then most likely your classpath is getting overridden or your application is using classpath specified in jar file or start-up script and to fix that you'll need to find the exact classpath used by your application.

Hi @sunil-kumar-ps,

Apologies for delayed reply but VDC Playground is currently compatible with Windows only.
