Key rule of posting, particularly for config questions: say what release you are using :)
In your original files, before you edited them, you should see stuff like
If you see that, you're using a fairly recent release. If so, undo your edits, restore the original.
Then start jboss with the -g switch:
run -g MyCustomPartitionName -c all
This will set system property jboss.partition.name, which will then set the value you want in all config files.
Thank you. It worked. The next post will contain the JBoss version :)
Have a nice day.
