What are Enterprise JavaBeans (EJBs)?
Enterprise JavaBeans (EJB) is a powerful component model for server-based applications as defined by Sun’s reference. This framework provides the basis for component based, multi-tier applications that benefit from the “Write Once, Run Anywhere”tm capability inherent in all Java-based programs. EJBs provide server-side functionality while separating the presentation layer from the business layer, simplifying application development, and speeding deployment.
