Some EJB containers allow file i/o and some don't. "bean law" says that file i/o is not permitted. We want to develop using jboss and want to keep our portability options open. We're thinking that we would prefer that devepers be strict about following "bean law" so that we could easily port to another server later if we wanted to. My understanding is that jboss is very forgiving about "bean law". How does one configure it to be strict?
