Thanks very much for all the help guys. Hanson - I have looked at beanlib a=
lready=2C as my goal here is populating DTOs from Entity beans and vice ver=
sa using hibernate. I attempted to get something working with beanlib-hiber=
nate but unfortunately due to the lack of documentation I gave up and tried=
 with BeanUtils - I could not get the hibernate2dto() methods working corre=
ctly. However=2C the BeanPopulator has done the trick here - so thanks agai=
n.

I like the look of Morph - great documentation here. If I get any time I wi=
ll give it a go. The main problem I am having is specifying how deep in the=
 object graph that my assemblers should go=2C and how to not overwrite exis=
ting entities in the database that are associated separately to the entity =
graph I am persisting. Bloody pain in the neck!

Thanks again=2C

Tom
