| 摘 要： | 近年来，随着网络技术及应用的发展．对中间件的需求也日益增多。虽然有很多成熟的分布式中间件技术，例如CORBA，但其过于复杂而且存在缺陷，很难满足企业应用的需求。因此，基于构件的中间件技术J2EE应运而生。本文首先从企业对分布式中间件的发展需求说起。介绍J2EE产生的背景及其总体框架。其次，本文重点分析J2EE的核心技术，服务器端构件技术EJB．阐述构件技术的基本理念和主要设计思想。最后本文比较了当前几种主流的基于构件的中间件技术：J2EE、CORBA、Microsoft．Net。

| Abstract: | Currently there is increasing need in the use of middleware with the development of the network technology and application. Although there have been some mature middleware technologies, such as CORBA, yet its complexity cannot meet the need of the enterprises application. So the new middleware technology, J2EE, come to being. The article will introduce the background and the architecture of J2EE firstly. As the most important character of J2EE, component model, especially the server side component model EJB will be introduced in detail secondly. At last we will discuss the flaw of J2EE and make some comparison. |
