I up the topic cause I still couldn't implements that DataBase Resource Bundle. I now have all the needed classes, following the steps described by pbrewer_uk, but I'm having trouble knowing what code to implements in what class. For example, I don't know what DBControl class is exactly supposed to do and when, and I don't know where to put the code to retrieve the messages from the DB neither (probably in the getKeys method of the ResourceBundle extended class?). Moreover, I don't know how to set up my Resource Bundle to be used instead of the default one (using Seam 2.0). Thanks for your help.
