| | Enterprise Java Beans |
 | | The EJB is hoped to be the preferred programming model for the new generation of Enterprise computing driven by the Web, where rapid deployment in a fast moving market place is seen as the key to success. | | | Java was next seen as a programming language that would allow programs to be delivered to Web Browsers, should they have JVM embedded in them. | | | The EJB Specification is now widely supported and this set of APIs, definitions and tool interfaces is now considered by many to be the new, open, forward looking way of programming business logic. |

| | Today Java Beans are widely used by the software industry to create user interfaces for all kinds of software. | | | Besides its name, the Java language and the idea of component based software re-use, it has little or no similarities with the Java Beans... | | | The idea is to create pieces of software that can be assembled together to create various kinds of applications. |

| | Client controls life cycle of a bean that involves creation of data in the database thus moving the bean from pool to the cache and removal of data from the database thus moving the bean from cache to the pool. | | | EJB 2.0 introduced the concept of local interfaces which work as local EJB without distributed computing capability (RMI/RMI-IIOP) while EJB 1.1 supports only remote EJBs. | | | For example if you deploy a cluster aware EJB application in three servers and if the first server is overloaded, clients are routed automatically to the next server depending upon the load balancing algorithms. |

| | These interfaces describe "what it can be asked to do" and "what it can ask others to do", along with general requirements for inputs, processing, and outputs, and it is intended that various implementations of the same component might be produced by many "component producers". | | | The overall communication is illustrated in EJB objects. | | | The term "component" generally refers to an object (which may contain other objects) which can be packaged and transported individually. |
