I'm wondering if JCR, aka the Content Repository API for Java, could be

No hands on.
The thing is, my use is not managing anything really document-like, but
nonetheless, it looks like the fundamentals of JCR are still a good fit.
I want to manage a catalogue for an e-commerce site - there's a
hierarchicaly structure comprising a root category at the top, with
subcategories below it, then at some level products, which in turn
contain SKUs. Each of these has a number of properties, things like
name, description, price, and so on. Possibly also images, although
those could be handled externally to the repository.
I would seriously consider JCR if I have data that are fundamentally
tree structured, because handling that via JCR is a lot easier than SQL,
ORM etc..
That's exactly what i thought too.
Now, on the site itself, this stuff is all read-only, with some simple
access patterns based on individual item lookups plus a few kinds of
query, followed by reading properties from the objects found. Here,
something like JPA or another ORM or OODB approach (or even just POJOs
stored with serialisation) is probably right - there's no need for the
complexity of JPA.
I don't consider JPA particular complex.
Quite right - that last JPA was a typo, and should have been JCR. My
mistake.
