I'm not really an expert on SDO but the issue with the WSDL that Tuscany generated is that it includes <xs:import namespace="http://sdo.commonj/"; /> Which doesn't resolve to anything sensible. The type dataObject is defined here [1] but even then that's in a different namespace. IIUC the dynamic SDO data object is intended to provide a dynamic set/get given element name style interface over an xml model. This allows you to define service interfaces that take arbitrary data types (imagine the scenario where you want to implement a service that process every message, regardless or message type, entering a message queue for example). Assuming that the dynamic object is backed by some known type model then I don't see why it shouldn't be persisted but I'm getting out of my depth re. what the Tuscany implementation actually does. The guy that knows about this stuff is away today I think so you may get a real answer on Monday.
