Using JavaBeans components as accessors to Enterprise JavaBeans components

In this paper we describe how the use of JavaSeans(TM) components together with Enterprise JavaBeans(TM) (EJB) components can help to develop flexible , mission-critical applications. We show how an application can be structur ed into three conceptual tiers, and how the use of JavaSeans components on the middle tier can help develop applications that can run in different cli ent/server environments (i.e., thin or thick clients). This eases the separ ation of server-side and client-side application development, each focusing on different problem domains. We also show that the additional level of in direction provided by using JavaSeans components as accessors to server-sid e business objects helps users of ISM SanFrancisco(TM) components to isolat e their client-side application development from upcoming changes in the un derlying back-end technology (i.e., the migration from today's SanFrancisco infrastructure toward future EJB-based releases of SanFrancisco).
