Hi, Chris.
You probably need to use the following "import.sdo":
<import.sdo factory="com.bea.proto.webservice.MedRecWebServicesFactory"/>
Thanks,
Raymond

Hi, Chris.
If you have <import.sdo location="wsdl/MedRecWebServices.wsdl"/>, it
means
that you prefer to use the dynamic SDO model derived from the WSDL/XSD. I
have two questions:
CW: Ahh, I did not know. Yet, if I remove the import the following line
throws an exception:
[NodeDataWriter}
Property property = xsdHelper.getGlobalProperty(
elementQName.getNamespaceURI(), elementQName.getLocalPart(),
true);
org.apache.tuscany.spi.wire.InvocationRuntimeException: Type '{
http://www.bea.com/medrec}getString' not found in registered SDO types.
With import.sdo, this web service call returns successfully.
1) Is the exception from client side or server side?
CW: Client. Occurs within Proxy.getPatient(...).
2) What's our business interface expecting? The strongly-typed java
class/interface generated by SDO or the dynamic DataObject?
CW: Strongly-typed:
com.bea.proto.webservice.Patient
getPatient(com.bea.proto.webservice.PatientpPatient) throws Exception;
Basically, the "import.sdo" needs to be consistent with your business
interface signature.
Thanks,
Raymond

Hey Raymond.
Our *client* scdl has:
<import.sdolocation="wsdl/MedRecWebServices.wsdl"/>.
Deserialized into the dynamic SDO makes
sense. XMLStreamReader2XMLDocument
parses the stream and creates a DynamicDataObjectImpl as it's root
object.
DynamicDataObjectImpl is aware of it's Patient context -
name=getPatientResponse, package=java: com.bea.proto.webservice, and
attributes. It's the root object that is returned from the binding.
Shouldn't there be an intermediate step that generates a Patient object?

Hi,
It seems that the exception is thrown from the target component and it's
related to the static/dynamic SDO (The incoming XML got deserialized into
the dynamic SDO instead of the generated static class which your
component
implementation code expects).
What does the "import.sdo" look like on the server side? Using "<
import.sdo
factory="..."/>"?
Thanks,
Raymond

Subject: Returning DynamicDataObjectImpl from web service call produces
TargetException leads to ClassCastException
Hi. After a successful invocation of a web service, a TargetException
occurs ("Cannot evaulate $Proxy35.toString()") after body is returned
from
JDKOutboundInvocationHandler. This eventually leads to a
ClassCastException:
java.lang.ClassCastException:
org.apache.tuscany.sdo.impl.DynamicDataObjectImpl
at $Proxy35.getPatient(Unknown Source)
at
com.bea.proto.webservice.client.MedRecWebServicesServiceComponent.getPatient
(
MedRecWebServicesServiceComponent.java:26)
Unfortunately I couldn't figure out how to get the full stacktrace from
TargetException.
Admittedly, this one has me confused. My first question is why is this
happening? My second question is when, if ever, does the SDO layer
convert
the DynamicDataObjectImpl back to the intended return object (in this
case
a
Patient object).
Thanks.
