Unless you are doing some type of Fat client or JSP, I do not understand why you would want the business objects not implementing some type of Remote Interface. Since you are doing EJBs, I am assuming you want the business objects which will act on the entity beans to be scalable. Making any beans that are not remotable, would kill the scalable design (assuming you want to start with say three tiers and be able to graduate to more tiers as the need arises). But I do not have near enough info to suggest a model for what you are wishing to do. You migth want to go to the javasoft web site and look at the models presented there. Good luck.
