I actually have met a few of the guys who came up with this: if there is one concept in JPA that recognizes practical needs, and doesn't get too theoretical, it's this one. It's much better, IMO, than the plethora of other JPA techniques for producing objects. You're not the first person in this thread who referred to object collections or aggregate values. I've not myself found straight SQL or JDBC any better than JPA for doing this stuff: if your app is Java then you ultimately need to translate into objects, and often object collections. I don't care to continually write that boilerplate myself. AHS -- When a true genius appears, you can know him by this sign: that all the dunces are in a confederacy against him. -- Jonathan Swift
