Sorry for the self plug, since we are on a topic of bean persistence frameworks, you may take a look at Cayenne at http://objectstyle.org/cayenne/. It is still in pre-alpha (mostly since GUI tools and user guides are still being developed). We based it on existing working design (WebObjects).
It works using XML mapping file (hence - GUI tools to help to create it). This solves 90% of persistence problems (and actually helps with a cleaner database design with normalized tables with fewer DB hacks and fewer cases where you would need to use stored procedures. etc.). I guess combining it with Jakarta frameworks like beanutils will allow to use it in an even more transparent fashion with arbitrary beans.
