I can run this properly locally but not on the server.
I don't know exactly how to explain my problem clear in a brief manner so instead I just listed all the steps
I went through below. Sorry that it's a bit long to read.
I'd be very grateful for any advice. Thanks!

Firstly, on my local computer:

1) I compiled the "Mini Template for absolute beginners" in release mode on B4J v8.3.0

2) I then copied the Objects folder from the Template folder of my ABMaterial folder and put it in a folder called C:\Test

3) I killed any Java process that was running (in case this app already running after compilation in release mode(?)

4) Then I ran this instruction on the command line
C:\Java\jdk-11.0.1\bin\java -jar C:\Test\Objects\Template.jar (OpenJDK 11 is in folder C:\Java)

5) I visited "http://localhost:51042/template" in the browser and the app was working properly

Then on the VPS:

On my Windows VPS I also have OpenJDK 11 in folder C:\Java. I visit the VPS using Windows RDP.

6) I uploaded the Objects folder to my Windows VPS and put it in folder C:\Test

7) I ran the same instruction on the command line there C:\Java\jdk-11.0.1\bin\java -jar C:\Test\Objects\Template.jar

8) But on the VPS when I visit "http://localhost:51042/template" in the browser I get just the circles you see in this app when it's loading.

Could you share/upload template.jar so I can test here in my computer to see if it works? Maybe we got a hint about the problem

The command prompt window on the VPS should have your applications logs. Copy and paste the log information here.

Please copy css, font, and js folder from www (project folder) to www in vps and try again.

Hi Alexandre, thank you but the Template.jar file is too big to process is the message the forum is giving me

Thanks Oliver, text from the command window is below

Did you copy copymewithjar.needs in the same folder as the jar?
Please copy css, font, and js folder from www (project folder) to www in vps and try again.

Hi Alexandre, I included the copymewithjar.needs.
The www folder has the exact same number of folders, files and is the exact same size on the server as on my computer.
I think I am putting stuff in the wrong place somehow, I'm just copying the objects folder, the one that contains the jar file and the www folder etc.

Hum... It seems that jar is looking for files in other folder.

Try execute the jar from C:\Newfolder\Objects

You guys are brilliant!
Took me a while to figure out what you meant but I think I got there eventually, it works!
(I hadn't realised that where the command prompt was situated made any difference if you used absolute paths.)
Actually the program works better over the internet than locally on the server where the "hello yourname" message doesn't appear.
Over the internet it works perfectly

Without the help you give here, I'd be nowhere with this. Thanks very much.

Once you "get" ABM - you got it.

Relative paths are "sometimes", not so relative. (like with images (icons), www, and downloads....
It can differ between WIN and Linux...

Debugging on your dev and running on production is the best way to see / resolve these issues.
I find it rather trivial compared to the other alternatives... I just go with the flow and what works - works...
