Who understand how Local Interfaces work ?

I'm studying Local Interfaces - I'd like to start

a discussion on this topic.

Local interfaces exist to provide a "local" view

of the bean and to avoid costly remote calls, but how

do I know that it has consistent values ? In other words,

if client access a "local" copy of the Bean, without

communicating with the Container, what do I get ? a cached

copy of the bean at that time ? If so, Local interfaces are

nothing else but a Value Object pattern

The point that I really cannot understand is how can the

Container ensure both a fast client-side Local interface

and database consistency.

Maybe the Container uses behind the scenes some callback

methods in order to keep the Local interface up-todate ?

Thanks in advance

Francesco
