Well, you said that bean instances are serializable because they implement
EnterpriseBean. But, as you said, Contexts are not serializable. So, bean
instances are not serializable because each of them contains one reference
to this context...
So, how could we expect to serialize a bean without specifying the context
as a transient field ?
Thanks.
