I´m not sure you can solve this particular problem the way DaveS
suggested, not without modifying the class anyway.
Even if you created a separate .jar and referenced that from your
client project, the GWT compiler wouldn´t understand the annotations.
My problem was similar to yours, and would be solved by creating a new
even simpler class like this:
Public class PhotoSetStoreDTO {
private String setid;
private String title;
private String description;
private String primaryPhotoURL;
public PhotoSetStore(String id, String title, String descString,
String photoURL) {
setSetID(id);
setTitle(title);
setDescrption(descString);
setPrimaryPhotoURL(photoURL);
}
}
Then use Dozer or a similar mapping framework to do the mapping
between server side and client side objects.
I haven´t been working with GAE at all to be honest, so there might be
a better approach.
