[jboss-user] [EJB 3.0] - design scenario, session bean usage

Hi, Using swing client talks to ejb 3 server. The swing UI consists of 2 major panels: menu tree nodes panel and content panel, which display the detail for the selected sub menu nodes. The server provides ex. 3 tpyes of services (thus the swing UI has 3 sub menu), using session bean talks with entity beans. some of the requirements are: session time out is configurable on the fly (by admin role), every content panel should be able to auto-refresh every 2 minute. As to the design scenario, I'm wondering: 1. Which is better in the following designs: A. one remote session bean per service, thus there are 3 session beans; B. a remote session bean talks with 3 local session beans, thus totally 4 session beans 2. using stateless or stateful bean(to satisfy time out), why, how?
