Did you check the response message from the WS? It might be the case that
XML payload is not conforming to the XSD which is used to generate the SDO.
I suggest that you open a JIRA and attach the test case there so that we can
debug.
Thanks,
Raymond

Subject: Re: WS bindings and SDO
Hello,
Raymond I've posted my interface in my last mail, after that
I did some tests.
When I send a SDO Object, all runs ok, but unfortunately for all SCA
users, return an SDO object is a problem even if HelperContext is
used.
For example:
1. SCADomain scaDomain =
SCADomain.newInstance("clinicalLaboratory.composite");
2. BiochemicalCircle service =
scaDomain.getService(BiochemicalCircle.class,"BiochemicalCircleComponent");
3. Laboratory lab = EntityFactory.INSTANCE.createLaboratory();
4. lab.setName("lab2");
5. biochemicalCircle.setLaboratory(lab);
6. Laboratory posibleLab = (Laboratory) service.getLaboratory("Lab2");
Line 5 works ok, SDO Laboratory object was send and name property was
read ok on server side.
Line 6 fails, I'm having always the same error:
java.lang.ClassCastException:
org.apache.tuscany.sdo.impl.AnyTypeDataObjectImpl
at $Proxy18.getLaboratory(Unknown Source)
Thanks,
Best Regards,

Hello Raymond,
My Interface is quite simple:
package services.bcircle;
import java.util.ArrayList;
import org.osoa.sca.annotations.Remotable;
@Remotable
public interface BiochemicalCircle{
ArrayList<String> getLaboratoriesNames();
model.sdo.Laboratory getLaboratory(String name);
}
I think that my problem is related with SDO HelperContext but I'm
confused.
Thanks,
Sebastián

Hi,
It seems that the SDO HelperContext is not correctly populated by
Tuscany
based on the introspection of the Java interface that references the SDO
types. Can you post the BiochemicalCircle interface?
Thanks,
Raymond

Subject: Re: WS bindings and SDO
Hello Again,
I'm getting the same error using ws binding.
If I try:
SCADomain scaDomain =
SCADomain.newInstance("clinicalLaboratory.composite");
BiochemicalCircle service =
scaDomain.getService(BiochemicalCircle.class,"BiochemicalCircleComponent");
Laboratory lab = (Laboratory)
service.getLaboratory("Lab2");
I have the exception:
java.lang.ClassCastException:
org.apache.tuscany.sdo.impl.AnyTypeDataObjectImpl
at $Proxy18.getLaboratory(Unknown Source)
but if I simple do:
BiochemicalCircle biochemicalCircle = new
BiochemicalCircleImpl();
Laboratory lab2 = biochemicalCircle.getLaboratory("Lab2");
All runs ok.
Invocation to BiochemicalCircle methods that not have SDO parameters
(or return them) works fine even if SCADomain is used.
Any in this list, know what I should do for solve this problem?
Thanks,
Sebastián

Hello Kevin, Simon,
cite:
Is the XSD you generated the SDO from included in your
contribution?
Yes I'm including the XSD, but how and when should it be used?
I verified if wsdl generated have included schema types and there are
ok. I thought that was enough if the wsdl have schemas included. Is
this correct?
Simon, you are rigth when you see AnyTypeDataObjectImpl instances is
becouse "If the ServiceFactory is not registered, the data (from the
inline schema of the WSDL) are then represented by
'org.apache.tuscany.sdo.impl.AnyTypeDataObjectImpl' "
What must I do? Use commonj.sdo.helper.HelperContext or not?
Any user in this list have errors like that?
Thanks for yours answers,
Regards,
Sebastián

I'm no expert on how SCA uses SDO, but I do understand the SDO side
of
this, which may help you or someone else get to how to fix this
within
SCA. The time that you see instances of AnyTypeDataObjectImpl
appearing is when an SDO deserialization operation has no metadata
within its operating context to describe an object it is trying to
deserialize, so it falls back on a very weak default model of data
embodied in the built-in AnyTypedataObject SDO class.
Either the SCA infrastructure or you must arrange for the generated
SDO factory associated with your Laboratory class to be known to the
relevant instance of SDO's HelperContext class. My feeling is there
is
most probably a way to influence SCA to do this for you, but I don't
know how. At the Tuscany SDO API level, the metadata registration is
done via the Factory's register(HelperContext scope) method, so you
could watch for calls to that method on the factory impl.

Hello, I'm trying to work with an SCA Composite that use ws
binding.
My component definition:
<sca:component name="BiochemicalCircleComponent">
<sca:implementation.java
class="services.bcircle.BiochemicalCircleImpl"/>
<sca:service name="BiochemicalCircle">
<sca:interface.java
interface="services.bcircle.BiochemicalCircle"/>
<sca:binding.ws
uri="http://localhost:8080/SCA1/MyServiceComponent"/>
</sca:service>
</sca:component>
The service retrieve a SDO object (Laboratory) that I generated
from
XSD without problems.
I deployed the project on Apache Tomcat/5.5.27 and I'm using this
service from a jsp page as follows:
(my includes)
.
.
.
<% SCADomain scaDomain =
SCADomain.newInstance("clinicalLaboratory.composite");
BiochemicalCircle service =
scaDomain.getService(BiochemicalCircle.class,
"BiochemicalCircleComponent");
Laboratory lab = (Laboratory) service.getLaboratory("Lab2");
.
. (more logic)
.
%>
In line
Laboratory lab = (Laboratory)
service.getLaboratory("Lab2");
I have the exception:
java.lang.ClassCastException:
org.apache.tuscany.sdo.impl.AnyTypeDataObjectImpl
at $Proxy18.getLaboratory(Unknown Source)
I have also tried to use the class commonj.sdo.helper.HelperContext
to
set a scope for my SDOFactory but I'm having the same exception.
Anyone in this list know to solve this error?

Sebastián
Hi Sebastien
Is the XSD you generated the SDO from included in your contribution?
I'm looking at the 1.x sample helloworld-ws-sdo-webapp and can't
actually see that the SDO types are specified explicitly but the XSD
used to generate them is included. Any of the SDO experts out there
know how we should be describing the SDO context in SCA?
Simon
