I haven't had great luck with making Java object persistence simple or elegant. The problem is that most real database applications that are maintained by database professionals require access to the DB to be done through a stored procedure interface. I haven't found a good way to make using an O/R mapping framework be any less work (over the long haul) than direct JDBC coding (the DAO pattern helps to encapsulate this, though).
There's been a lot of activity in the Open Source world over the last few years in this space; time to check them out again to see if there are any serious contenders for work on real systems that have to integrate with things other than Java apps in a "green field" project.
