P.S. The reason the POJOs is of interest separately from the JPA goop is that you can feed that into the schemagen mvn plugin and out pops a reasonably decent xsd. This allows you to plug into existing XML tool chains -- if you use those. Schemagen barfs on the JPA. i could never get Oxygen to do what it promises to do with SQL schema. So, this seems the best/simplest way to get XML stuff to bear beginning from the SQL schema.
