J2EE核心技术研究及其在校园网上的应用与实现
|
摘要
J2EE是企业计算领域的一个非常重要的开发平台，它在快速开发分布式的、多层的、高性能的企业应用方面具有显著优势，同时它也是目前大型的电子商务的首选平台技术之一。本文对构成J2EE平台的核心技术逐一进行了探讨，着重研究了EJB组件技术、JMS、JavaMail、JDBC等技术内容。通过研究作者发现，J2EE的先进性主要体现在它的体系结构和EJB组件上，因此在核心技术的研究方面，作者更多的注意力是放在EJB组件技术的开发和技术本身在体系结构中的位置和作用上。本文的另一个重点是关于J2EE技术在高校校园网的应用，作者首先从理论上给出了J2EE技术在校园网上的应用方向和应用前景，然后通过一个具体例子进行了示范说明。该例子是一个应用在校园网上的二手物品交易平台，尽管它只是校园网上一个很小的应用，但它具有典型的J2EE体系结构，使用了J2EE平台大多数的核心技术。通过它作者一方面展示了J2EE的各项核心技术的内容和特点，另一方面也展示了开发J2EE应用程序的全过程，包括EJB组件开发、建立开发环境、部署应用程序和测试等。这个例子可以说是在校园网上开发J2EE应用程序的一个缩影，它里面使用的方法和技术在开发校园网上的其它应用时也常常会用到，甚至在开发大型电子商务应用时也是如此。
J2EE is a very important platform for enterprise computing. It has distinct advantage for quickly developing distributed, multi-tier and high performance enterprise application. It is also one of prior technology platforms which use to developing large e_business projects now. This paper introduces most kernelled technologies of J2EE platform. Some of these technologies, such as EJB component technology, JMS , JavaMail and JDBC, are stressed discussed in the first part. By research, the author find that the advances of J2EE mostly embody its architecture and EJB component. So more attentions are given to how to develop EJB component and these technologies' location and function in J2EE architecture. The application of J2EE on campus network is another emphasis in this article. It is only a small application on campus network, but it has typical J2EE architecture and most core technologies are also used in the example. The author first discusses application aspect and application foreground of J2EE on campus
network in theory, then a practically illustration is given for demonstrating J2EE' s application on campus network. This illustration is a second hand goods bargaining platform, which is a mini e_business system. In the illustration, the author lays out many contents and characteristics of the core J2EE technology, gives out the full processes of developing J2EE application program, involving developing EJB component, setting developing environment, deploying application program, web testing, and so on. The illustration is a epitome of developing J2EE application on campus network, and these methods and technologies in this case are often used by other applications on campus network, indeed they are also used in large e_business projects.
