B4J Question [B4JServer] Could not locate b4xV5.ini … [ERROR]: missing the html files.


Please note that I am new to B4J. I have made progress but I am stuck in a frustrating place right now. Any help would be much appreciated. Here is the issue:

1. I am working in a Windows 10/VirtualBox (Ubuntu Server) environment.
2. I am compiling my Win 10 B4J BANanoServer WebSocket PWA based project with the "Recommended: OpenJDK 11 + OpenJFX 11"
3. On the Ubuntu Server, I copied over the Linux version of OpenJDK 11 + OpenJFX 11 (linux_jdk-11.0.1)
4. I am logged into the Ubuntu Server with full sudo rights, all required ports are open, and full rights are on for all files/folders involved in this test/learning project.
5. On the Ubuntu Server side, I have the project jar in my /home directory and the HTML in the /home/www directory.
6. The only files and folder that I moved into the Ubuntu Server are the jar file, the server.ini file, and, of course, the www folder and its contents (please see the attached image of my Win10 B4J project folder - do I need to move any other files or folders (besides the ones I mentioned) over to the Ubuntu Server side?).
7. I start the Ubuntu Server jar with this line: sudo home/java_linux_1101/bin/java -jar home/PWA_ServerClient2.jar (I use line instead of the nohup one because I can immediately see the results in the console for testing).
8. After I start it, I can see a "Resource Not Found" message in the web browser, and the web browser console shows that the browser does hit the server but with "GET 404 (Not Found)" and "Navigated to".
9. This is what I get on the Ubuntu Server-side (please note that I did include the www folder and the HTML files as noted above):

Please help if you can (thanks).



By the way, when compiled and executed completely on the Win10 side, everything seems to work fine.
