Ji Jakob, yes this is a persisted class. The jdo-annotations, tells datanucleus to persist this in the datastore.
Yea, I´m sorry but you got me right. I ran into this too, when I started to work with GWT and GAE. The solution is quite simple, you already said it. Make a so called: "DataTransferObject" for each persisted class. This is a Design Pattern .. the DTO-Pattern. And yes, it is not a good solution. If you have time, and good Java-knowledge you can code a Code-Generator, that generates the DataTransferObjects from each persisted class. It´s a good solution if you have many classes, that need DTO´s. Here you can just maintain the perissted class und regenerate the DTO. I foun d a nice solution, for me: I store the object (in your case DTO) in the datastore. So my persistet class looks like this: @PersitenceCapable class LetterDataBaseObject @Persistent Key key; @Persistent String myID; @Persistent(serialized = true) Letter myLetter ... I generate a searchString, so I can still query my object. For the beginning I would simple use the DTO-Pattern. Greets Alex P.S.: what about your import error?
