Hi All,
I have a probably silly question about a EMF usage scenario in a distributed JEE environment. Suppose I used EMF to generate Java classes from a XSD grammar; now I would like to use these classes also remotely, from a Java EE client application. The problem is that generated classes are not Serializable by default so I'm wondering if this scenario is somewhat supported by the framework and, if not, which is the recommended way to implement a usage scenario where generated domain model classes are of for both the server BL and the client UI
Thanks a lot for the clarification
Best Regards,
Patrick

Patrick,
Even if that bug is addressed, I think it will be far more efficient to
serialize as XML. You could define a wrapper/container class that has a
reference to an EObject and specialize its serialization code so that
the whole containing resource is serialized as XML... If you're going
to transfer just bytes, you'd be way more efficient to use
BinaryResourceImpl.
