This is very interesting. Can u give some hints as how to go about writing this Generator?

Thanks,

I used to use overlay type heavily (returning JSON from a Spring
MVC/Jackson backend) and it worked quite well. Although I found it
quite limiting to be unable to model "real" class hierarchies (JSOs
must not be subclassed). I really do this a lot on the server side. I
also really like to use the enhanced for loop for Lists and just do a
new Foo() instead of some tedious Foo.create(). Last but not least I
don't have a "Generate getters/setters" in Eclipse for my JSOs :)

All this led me to write a Generator which inspects my models ("real"
beans) and emits JSON mapping code handling simple properties, object
graphs and collections. That way I can work with real beans and
collections of beans in my (business) code and do the mapping from/to
JSON in my service/DAO layer (still sending/retrieving JSON to/from my
backend).
