基于Web的中间件系统集成框架--应用服务器的研究

摘要

After introducing the techniques of application server, component and framework, explanations are given as to how to build up a high-performance, scalable, and robust infrastructure of Web-based distributed application server by combining the open, cross-platform, and cross-language capabilities of CORBA with the transactional business logic of Enterprise JavaBeans(EJB) technology. A system is made of component container, management console, transaction service, external resource management, naming service etc. It possesses the characteristic such as easy to develop, easy to manage and easy to load services etc. Introduced in this paper are the theory background, system architecture, key technology and application domain framework on it etc.%以“八六三”项目为背景，在探讨应用服务器技术、组件和框架技术的基础上，通过结合CORBA开放性、跨平台、跨语言的特性和EJB业务处理能力，设计并实现了一个可伸缩、健壮的、支持Web分布式应用的中间应用服务器系统平台，其功能包括：组件容器、管理控制台、事务服务、外部资源管理、名字服务等；并在实际中得到了初步应用，取得了很好的效果.与其它方式的服务相比，它有着易于开发、易于管理和易于加载服务等特点.对其理论背景、体系结构、关键技术以及其上的应用领域框架等进行了全面的研究.
