Enterprise Java Beans

Overview

Enterprise JavaBeans (EJB) is a standard server-side component model. The component model consists of transactions, distributed objects, concurrency, security, persistence, and resource management. A Component written to that model has a robust server environment and should run on any platform and server adhering to the EJB specification.
