Hi Kelvin
Yes, this partly represents my szenario. It works for
me in a standalone JVM. It works also within a simple
servlet szenario. It doesn't work in a servlet/ejb
szenario when I run an initialization step when
starting up the ejb module such as:
HelperContext hc = HelperProvider.getDefaultContext();
Factory.INSTANCE.register(hc);
This initialization is required in order to have all
types registered for subsequent rmi/iiop calls. Btw,
without having a datagraph in my SDO hierarchy, it all
works fine, even in the servlet/ejb szenario.
If I omit the initialization step in the ejb, the
servlet works fine but the ejb fails when
deserializing the serialized datagraph.
To me this looks like something (the change package)
registered during the ejb initialization in the global
registry is not visible to the servlet afterwards.
Thanks Erich

Hi Erich,
I generated code from your schema and tried the
following lines of code,
which executed without failure ...
*public* *void* testErichsProblem() *throws*
Exception {
PublicationDataGraph pdg =
ServicesFactory.*INSTANCE*.createPublicationDataGraph();
DataObject dob = (DataObject)pdg;
ChangeSummary cs = dob.getChangeSummary();
cs.beginLogging();
}
does this represent a distilled version of your
scenario?
Regards,Kelvin

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.
