this may be a silly question.. stateless session beans are obviously the highest performing enterprise beans, and most documentation says something along the lines of "usually only a few instances can service hundreds of concurrent requests." i'm wondering though, if these beans have no state, why would an ejb container _ever_ need more than a single instance to service all requests?
They have no "client" state.
They can have internal state such as a database
connection.
