Can you give a more complete code snippet of what you're doing?

Seems that you've registered a dynamic EPackage with the global EMF package registry or the CDOSession's package registry. Are you sure that your generated version of the model is properly registered? And not removed by subsequent manual registration of a dynamic version?

Please try the following and tell us the output of:
System.out.println(transaction.getSession().getPackageRegist ry().getPackageInfo( "http://.../sro").getPackageUnit());

I'm sure we'll sort it out ;-)

Hello,
Here is the return : org.eclipse.emf.ecore.impl.EClassImpl@c3af8c (name:
SROProject).
So, I will search around registration.
Regards

I have to anonymize the file before.
The goal of my job is to be able to load huge xmi files (many hundreds
of bytes).
To do so, I've tuned (subclassed) the XMIHelperImpl and SAXXMIHandler
classes to read the objects, then, in a second step, make references
between objects.
I've done this with a small file, with the problem described here.
For huge file, I will add commits after reading N objects and M
references. Doing this, I need to retrieve objects from the store.

I think the problem here around here because
getEFactory().getSROPackage(); return null
and
transaction.getSession().getPackageRegistry() shows me that packageInfo
is null also.
So i think I've forgotten one step invoking my EFactory and/or my EPackage

Hello,
Some good news for me. The job is not over but this part works !!
The xmi file I was provided was referencing the ecore and not the uri.
So, I changed this part.
I also had a bug in my code passing the source resource contents to the
target resource contents.
Thanks a lot to have helped me to think about my code.
Regards
Stephane
