I'm really not sure, but I'd recommend checking out the Appengine google group first... http://groups.google.com/group/google-appengine-java?hl=en
There's over a hundred posts a day there, so I'm sure someone there with a little more expertise than yours truly will be of more help. Out of curiosity, have you already tried sending your persistent data classes down the wire? Cos.... There's a lot of discussion about it, and some workarounds {basically, the only ways I could do it was with Ray Cromwell's various hacks, or a drop-in called Gilead}. You might find that using the same beans to be nigh impossible without making them non-detachable {read: you can send an object to the client, modify it and send it back to the server to save without copying the object, or manually copying the data from every field}. ...Check the other group, like I said... I'm no expert. Of course, Ray Cromwell IS, so if you can find his Google-Groups profile, try clicking on some of the threads he posts on... You'll be glad you did! --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
