Stateful Session Beans

[GlennODickson]

Can anyone tell me the following about stateful session beans ?     1. Who calls them, I am to understand that these beans should be called by the specific client (stub-client)?     2. Can a facade call these and hide its use?     3. Do they have to be called from the client and if not, what are the common ways in which these are used.     4. Who exactly calls these (client side apps etc) and how I structure they use properly (according to how that are to be used correctly!)       I do understand that these are to hold states of maybe shoppingcart details for one user/client.   Can someone please shed some light I am not new to J2EE but just haven't used these type of EJB before and would like some professional advice.   TIA Glenn
