You might try to see and check if this fix is included in your Tuscany version. (I haven't got around to retesting this myself.) 2) Furthermore, possibly you need to import the missing resource mentioned in the stack trace in a META-INF/sca-contribution.xml file (<import.resource uri="foo.xsd"/>) and use import.sdo in your composite (<dbsdo:import.sdo location="foo.xsd"/>). I did have to do this for my own SDO's defined by a backing xsd-file in order to be able to serialize them over a service boundary. Perhaps a similar thing applies even if you do not have an xsd-file, but simply need to import the namespace. -- Sebastian
