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,
Sebastián Groh
