Has any one successfully configured MySQL data source using JBoss 4.0?

Much of the JBoss 3.x data source configuration instruction does not apply to 4.0 any more, e.g. there's no longer the deploy/jms directory, and mysql-service.xml is replaced by mysql-ds.xml. I hope these are the signs to simplify the configuration. However, the configuration HOW-TO should be provided along the distribution.

If any one had done that with success, please share your HOW-TO.
