First I have to say something. It has some time that I have attempted
to introduce cayenne here in our department and one of the main
arguments that has impeded me was the support to the programming with POJO.

But in this first project we are not using this option, being still in
phase of learning and mainly for this characteristic not available in
version 3.
But I have to admit, as DBA I find that these characteristics
(annotations, POJO, JPA, etc), they do not beat the modeller and the
useful technique to avoid overwriting of the custom code.
Thanks for your attention!

PS.: We will try to switch to Cayenne 2.0.3 and see if the app works.
