the documentation be better, sure. Could the examples be better, maybe --
they are pretty good. Any new technology has a learning curve -- if you
spent the big bucks for one of the commercial O/R mappers you might very
well find that you had as long or longer a learning curve. At least with
Cayenne you have access to the source if you are having problems. The
technical support here and from Andrus is incredible.
I have looked at several commercial and "free" O/R mapping products and
think that Cayenne is probably the best I have seen. I do find it fairly
intuitive although the jump from thinking about DB from a relational
point-of-view to an OO viewpoint is not easy. In relational, I tend to think
from the top-down while I find in OO that "thinking" from the bottom (or
nearly so) up works better.
I would suggest giving it a weeks worth of time or so to try it out. I tend
to use such tools on existing databases to reverse engineer the O/R mapping
but that is not the best approach (most relational databases are not very
