StringPropertiesService gives the user the ability to set params all in one place. EJB2.x provided this capability and we have several customers who requested it in EJB3. The properties are configured in the StringPropertiesService What are you seeing fail or think will fail? The warning you are seeing is just saying that a ${...} pattern was found and the StringPropertiesService is not running.
