I’m having a problem. I would like to create Document object, and I would like to have a user property with com.google.appengine.api.users.User type (on GAE’s docs site, they said we should use this object instead of email address or something else, because this object probably will be enchanced to be unique). But now the object can’t be compiled by GWT, because I don’t have the source for that object.
How can I resolve the problem?

I was searching for documents about DTOs, but I realized that maybe that’s not the best pattern I should use.

What do you recommend?

Very thanks for your help!

    to avoid DTOs for objects with com.google.appengine.api.users.User inside you can probably use the work from
    http://www.resmarksystems.com/code/
    He has build wrappers for the Core GAE data types (Key, Text, ShortBlob, Blob, Link, User). I’ve tested it with datastore.Text and it worked well.
