For what it's worth, I use java.util.Date for all of my java classes,
and TIMESTAMP(6) (Oracle) for all of my jdbc types in a Cayenne 1.1.4
project. I did have to make a minor patch to the types.xml file, and
the 1.1.4 modeler doesn't generate the right sql so I have to modify
it by hand afterwards from " DATE " to " TIMESTAMP(6) ". This works
for optimistic locking on date fields under Cayenne 1.1.
I can't remember what I've been doing for my 1.2 projects. I suspect
I've been using DATE instead.
