Linux server: Centos 7
What I've done:
1. Download Java sdk 11, linux version to my Windows 10
2. Unzipped it with 7Zip to a folder named java11 which contains the bin folder as one of its child folders
3. Uploaded entire java11 folder to my server at /home/user1/java11
4. Compiled my test app in release mode and the resulting jar file is test.jar
5. Uploaded test.jar to /home/user1 folder
6. Ran the following terminal command
B4X: 
nohup /home/user1/java11/bin/java -jar /home/user1/test.jar >nohup.out &

And I got this log
nohup: failed to run command '/home/user1/java11/bin/java': No such file or directory
Click to expand...
What am I missing?

Thanks in advance!
 
Solution
I ended up installing java using terminal even though the instructions indicates that installation is not needed.

After the installation, everything works. I don't need to specify java path any more
B4X: 
nohup java -jar myjar.jar >nohup.out &

This has to point to the location of java on your vps. I doubt it's correct.

That's the location of java I uploaded and I for this post replaced the actual username with "user1" for simplicity

You have to confirm. The error message shows that the path or file does not exist.

Mine is like this;

user1/java/jdk-17.0.1/bin/java -jar

java11/bin contains those usual files such as java, javac, etc.

I'm not familiar to linux and my vps is fully managed and as a result I might have made some mistakes not obvious to me.
