Some time ago I created a small sample project using Thorntail and JBeret:
https://github.com/jberet/numbers-chunk-thorntail

but that does not use any datasource.

I haven't followed Thorntail for a while, so not familar what mechanism it supports.

Maybe you can try passing these datasource propertiesn as system properties (-Dxxx=xxx) as part of the command in your yaml file.

In your job xml you can reference these system properties as

#{systemProperties['x']}

Hello,
Thanks for replay. I have to solve it not using system properties because passwd shouldn't be send this way.
