Picture the EJBObject as an abstract idea rather then a physical
implementation. Its easier to understand, and since each container vendor
can implement it however they want, its more accurate. For instance, an
application server written in Java will implement this very differently then
say one written in C like EAServer to optimize the peformance of this
dispatching. The point to keep in mind is that the EJBObject is the logical
implementation of the servant and acts as a glue to the physical bean
instances.
Such as an entity bean in contaienrs like EAServer which create multiple
physical instances to represent single EJBObjects, like a row in a database.
The EBJObject I find easier to think about in a logical way rather then how
did that vendor physically implement it.

Subject: EJB Object implementation
> Hello all,
