There is a bunch of online shopping solutions out in the wild, most of
them proprietary and/or expensive (I wonder whether there are any
usable open-source JEE based web shops out there?)

This is likely to be part of either what the shop system you will make
use of offers, or part of your specifications of what your shop system
is likely to do.

You could go with more than two different states per item in your stock
("available", "reserved" == someone put it in its cart but hasn't
checked out yet, "sold" or something like that). Of course, you have to
be sure to handle these states in a meaningful way, i.e. take care to
"expire" product reservations after a sane amount of time has passed
(to deal with people who fill up their cart but never actually check
out and/or buy anything...).
Are you about to build a system like this? If so, how much of the
specification / design work did you do so far?
Cheers,
Kris
