Hi I am testing with the SDO beta-1 code.
I generated static SDO classes with an embedded datagraph by extending the BaseDataGraphType as described in the SDO 2.1 spec using the following XSD: <xsd:schema xmlns="http://www.w3.org/2001/XMLSchema"; targetNamespace="http://abc.com/services"; xmlns:tns="http://abc.com/services"; xmlns:sdo="commonj.sdo" xmlns:sdoJava="commonj.sdo/java" xmlns:sdoXml="commonj.sdo/xml" sdoJava:package="com.abc.services" xmlns:xsd="http://www.w3.org/2001/XMLSchema";> <xsd:complexType name="PublicationDataGraph"> <complexContent> <extension base="sdo:BaseDataGraphType"> <xsd:sequence> <xsd:element name="test" type="xsd:string" /> </xsd:sequence> </extension> </complexContent> </xsd:complexType> <xsd:complexType name="ModifyPublicationInput" <xsd:sequence> <xsd:element name="PublicationDataGraph" type="tns:PublicationDataGraph" /> </xsd:sequence> </xsd:complexType> </xsd:schema> After I instantiated the top level DataObject (ModifyPubicationInput) containing the embedded Datagraph, I tried to beginLogging which causes the following exception in org.eclipse.emf.ecore.change.ChangePackage$Literals.<clinit>(ChangePackage.java:903). The same exception also happens when I try to serialize the toplevel DataObject to XML or when I try to send it via RMI/IIOP to an EJB.
