The private setters is a nice addition, but not really helpful in our
situation because the fields actually don't have setters at all; the object
is filled in through the constructor call.
I did pick up on some interesting conversations that you had with the the
guy who wrote O/R Broker, which seems to have a nice pattern for dealing
with constructors and complex loading statements (like loading up a field
based on the contents of another field). Hopefully we'll see something
similar in IBatis in the future.
Thanks for your help ... :-)

As a temporary alternative we do support private setters as of 2.2.0.
Constructor injection is supported in the .NET version. The two codebases
are somewhat similar, so we could always check on their approach to it.

I remember some folks asking about this, but no commitment to do it. It
would require quite a change to the way iBATIS processes result sets.
Translation: don't expect this anytime soon.
BTW, the Sun patterns web site has some information about an immutable
transfer object pattern here:
http://java.sun.com/blueprints/patterns/TransferObject.html
The basic idea is that you create an interface for the immutable part, and
a mutable static inner class for initializing. This does work with iBATIS.
But one warning - we used this pattern on my team for a while and everyone
(me included) HATED it. So we eventually went to simple JavaBeans with
getters AND setters.

Mmm ... no that's not quite it.
I have a set of VO classes that are immutable. This means that all the data
is added at construction.

I am not finding docs for it at the moment, either. I think that the
ResultObjectFactoryTest unit test does what you want. Take a look, and
see - if it is, please feel free to add a page to the WIKI
(http://opensource.atlassian.com/confluence/oss/display/IBATIS/Home )
on how to use it.
