Thanks,

In this case,  I'm using whatever implementation of the SDO 1.0 spec IBM 
included in
WebSphere App Server v6.1.0.13 - 
..\plugins\org.eclipse.emf.ecore.sdo_2.2.0.v200609210005.jar
I believe this is almost certainly "pre Tuscany".


Would you know if the following behavior is "working as designed"?

In an EJB client, I can generate "static" SDOs (that inherit from 
org.eclipse.emf.ecore.sdo.impl.EDataObjectImpl)
and create an org.eclipse.emf.ecore.sdo.impl.EDataGraphImpl with the 
SDOFactory, 
and populate its root Object and contained SDOs using
generated IBMFactory, IbmPackage and "static" SDOs.

I pass that EDataGraph as a parameter to a method defined
on the remote interface of an EJB.  After serialization - RMI/IIOP - 
deserialization, when
I inspect the EDataGraphImpl in the EJB method, I find that each contained 
EDataObjectImpl has
be replaced by a DynamicEDataObjectImpl. 

As a result, I can't (figure out a way to) use
the generated static SDOs in the EJB method.

Regards,

Gary

In a) you should be using commonj.sdo.DataGraph (implementation class 
org.apache.tuscany.sdo.impl.DataGraphImpl) because 
org.eclipse.emf.ecore.sdo.EDataGraph is a specialized interface in the SDO 

1 implementation at Eclipse that isn't supported in Tuscany. (if you have 
both available, it sounds like you're somehow running both SDO 1 and SDO 2 

concurrently in your environment.)

That aside, you should be able to use static classes in the EJB method, as 

long as they've been registered (e.g., StaticFactory.register() was called 

for the EJB scope).

Frank.
