"You might change the standalone-full.xml by hand."
- That is what not happening ! Whatever new things I write in that file just vanishes as soon as I start the server. I will be too glad if those changes remain.
That is why started to write on all the standalone-full.xml versions I could lay hand on. Even when i did it, JBoss, it seems, has a hidden copy and replacing my new file with that one as soon as it starts.
