A lot of ORMs are designed for ease of persisting objects, not ease of realising databases.
Though I haven't used it, so can't guess whether it would be a good match for your needs or not... one tool I think may
makethe database to object mapping easier is ActiveObjects.

I use and quite like Spring-JDBC. Among other things, it makes JDBC use much less verbose.
In Java, a lot of projects use some form of data-binding between their GUI and Objects, then an ORM to persist those
Objectsto a DB.
