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.

Kelvin.

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?
Regards,
              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?
