Setting the fetch batch size to a value greater than zero means that OpenJPA will return you a result that will stream results as they are requested.[1] This works fine when you are processing a result set locally... when you try to stream this result out to a remote client, OpenJPA doesn't have the ability to request additional data from a remote client. I'd recommend getting rid of the fetch batch size configuration.
