Are you trying to transport a query result set from GAE to GWT? Sorry but JDO/JPA persistent objects are not serializable (just like EntityBeans). You will need to do something to make the objects portable. I suggest checking out Objectify or creating your own Data Transfer Objects. http://code.google.com/p/objectify-appengine/
