List or ArrayList/concrete type

Hua Zhang <hzhan...@gmail.com>: Dec 04 03:30AM -0800 Is this 'concrete type' als valid for a DTO object in GWT-RPC?   For example, I have a TestDTO object, which needs to be transferred via GWT-RPC.               *public class TestDTO implements IsSerializable { public ArrayList<String> data; public List<String> operation() { return null; }}*   If I understand correctly, data field needs to be a concrete type. How about the method operation, can I return here a generic List interface?   Best regards,   Hua
