Enterprise beans are the J2EE components that implement Enterprise JavaBeans (EJB) technology. Enterprise beans run in the EJB container, a runtime environment within the J2EE server. (See Figure 5.) Although transparent to the application developer, the EJB container provides system-level services such as transactions to its enterprise beans. These services enable you to quickly build and deploy enterprise beans, which form the core of transactional J2EE applications.
