[OT-kinda] How to perform equivalent of Cayenne prefetching for pure JPA application?

[Mike Kienenberger]

Is there a way to perform the equivalent of Cayenne prefetching for a
pure JPA application?
I've just started working with a JPA project, and to pull in 3
records, it ends up executing over 700 sql statements, many of which
seem to be the same sets of dependent records pulled in, one record
per query, a problem I'd solve in Cayenne using prefetching.
