基于J2EE的分布式技术及在分布式制造系统中的应用

Distributed technology based on J2EE is applied in distributed manufacture system

针对传统C/S结构存在的弊端,传统的解决方案往往是基于3层的B/S结构。但是,随着企业应用系统越来越复杂,系统与系统之间的集成问题已变得尤为突出。针对以上问题,本文提出了基于多层结构的J2EE标准的分布式企业应用系统开发思想,并详细介绍了J2EE的体系结构和作为J2EE的核心技术的EJB规范。本文最后通过一个软家装制造企业的分布式制造系统开发来说明基于J2EE平台的开发技术。

Based on analysis of defects in traditional architecture of Client-Server(C/S), the traditionalresolution suggested is Brower-Server (B/S) architecture based on three tiers. However,with enterprise application system becoming more complex than ever, and the integrationproblem between systems becoming more urgent than ever, the B/S architecture has nolonger been a perfect solution. In order to resolve these problems above, this articlecome up with Java 2 platform, EnterpriseEdition (J2EE) standard based on N-Tiersstructure which fits development of distributed enterprise application system. The articleplaces emphasis on the architecture of J2EE and EJB criterion as core technology inJ2EE.Finally this article gives an example of development of distributed manufacturesystem in soft decoration manufacture enterprise to demonstrate development technologybased on J2EE.
