Database JPA Entity Management [message #1387149]

I am fairly new to development with JPA entities, but am finding many advantages including turning out code quicker. I usually prefer to focus data model development within database visual tools though, so I am looking for the best way to update entities from the database on a regular frequency. For example, I update my database model through a tool apply the changes to the database, and then want to update my entities from the tables. However I have a number of NamedQueries and JAXB annotations that I don't want to lose. How do I sync these up without loosing my changes? Do I create a superclass where all of these properties are inherited (will this work), or do I just create the automatically generated entities to another package and then use a merge tool to update. I am looking for the most efficient method to manage these types of changes. Or should I be using another mechanism?

You might get more response in either the Dali or EclipseLink forum groups, which tend to have JPA experts hanging out in them. Also note that yours is not an Eclipse-specific question so I suggest asking on a general programming forum such as StackOverflow.
