By the way, if you migrate your SQL stuff into Hibernate, and if you use the StatelessSession API of Hibernate 3.x, you will get a very simple JDBC command persistence layer, without all the fancy new semantics of a "full" ORM (no object dirty checking, no caching, no cascading, etc). Hibernate then basically just acts as a command bridge for SQL operations, but returns and accepts domain objects.
