Sanjith, I'm using GWT on GAE and I also have my data model classes with JDO annotations. I have those classes reside under client/domain and GWT 2.0 handles/ignores those JDO related annotations well and i don't have to use Dozer or another framework in order to be able to use those classes on the client.
If you need more help, please let me know.
