19. Enterprise JavaBeans (EJB) EJB is an architecture for component-based transactional distributed computing. An enterprise bean contains business logic that operates on the enterprise’s data. Client access is mediated by a Container. There are three kinds of enterprise beans: session beans, entity beans, and message- driven beans.

20. Enterprise Bean Objects Session objects: for a single client, short- lived, … Entity objects: object view of data in the database, shared by multiple clients, long- lived, … Message-driven objects: triggered by a single client message, short-lived, stateless, …

21. Client View of an Enterprise Bean Home Interface: methods for creating, removing, and finding bean instances Remote Interface: methods callable by the client Object Identity Metadata Interface: mainly for dynamic invocation Handle
