,
I was wondering if there is an alternative to using DTO's to send
persistent objects from server to client and vice versa that is
compatible with Google App Engine. The objects are persisted through
JDO. I would appreciate it if you could provide some suggestions.
Thank you.

What is the problem with DTOs that you're looking to avoid? The
duplication? Being more specific might help people give you relevant
suggestions.

Yes, I'm trying to avoid having to duplicate, and convert between the DTO
and the persistent object, because I'm worried that the increase in number
of DTO's will result in too much repetition of code.

You can try RequestFactory.

Totally valid concern.
A lot depends on your situation and the purpose of your app. One
alternative is the RequestFactory. I've not used it myself, however.
Another alternative is to just detach your domain objects and send them to
the client. You'll want to be sure there's nothing in there
Thank you for your suggestions. I will look into them promptly.

I exchange directly JPA annotated POJOs between the client and the
server, and I persist the same objects within the servlet. GWT
compiler ignores the annotations, the servlet use them for
persistence. I do not use RequestFactory (I've not yet studied it,
probably I'll use it in the future but for
What's JPA implementation are you use?
