初始的JavoBeans的定义描述了主要运行在客户侧的客户／服务器系统之上的Java组件的行为和属性，企业JavaBeans的1．0版本的定义更改这种情况，企业JavaBeans是为创造可扩展的，多功能的，分布的应用提供的组件体系结构，而且它让创建动态的、可扩展的应用服务器成为可能。最近业界都表现出对企业JavaBeans（EJB）技术的关注，开始制定计划去实施这种基本的组件。自从1998年3月企业JavaBeans（EJB）1．0规范发布以来，她给业界带来了巨大的影响，许多公司，如：Oracle，Borland，Tandem，Symantec，Sybase，以及Visigenic等都纷纷响应，表明并发布了支持EJB规范的产品。这里我们将去认识企业JavaBeans（EJB）究竟是什么，从总体上分析EJB究竞和原先的JavaBeans组件模式有什么区别，从而讨论为什么EJB能够产生出如此巨大的影响。
The initial definition of JavoBeans describes the behavior and properties of Java components that run primarily on client-side client / server systems. As the definition of Enterprise JavaBeans version 1.0 changes, Enterprise JavaBeans is designed to create scalable, Multi-functional, distributed application component architecture, and it makes it possible to create dynamic, scalable application servers. Recently, the industry has shown concern for enterprise JavaBeans (EJB) technology and began to make plans to implement this basic component. She has had a huge impact on the industry since the release of the Enterprise JavaBeans (EJB) 1.0 specification in March 1998, and many companies such as Oracle, Borland, Tandem, Symantec, Sybase, and Visigenic have all responded And released a product that supports the EJB specification. Here we will go to see what the enterprise JavaBeans (EJB) is and analyze the differences between EJB Research and the original JavaBeans component patterns in general to discuss why EJBs can make such a huge impact.
