I post my code once again:   	

	HelperContext hc = HelperProvider.getDefaultContext();
     	PersonFactory.INSTANCE.register(hc);
     	
     	DAS das = DAS.FACTORY.createDAS(getConfig(configFile));
     	
         Command readPerson = das.getCommand("getFirstPerson");
         DataObject root = readPerson.executeQuery();

         Person p = PersonFactory.INSTANCE.createPerson();

         p = (Person)root.getDataObject("Person[1]");

The exception is:

java.lang.ClassCastException: 
org.apache.tuscany.sdo.impl.DynamicDataObjectImpl cannot be cast to 
sdo.Person

Best regards,
