现有的 Web计算体系结构在性能和功能上无法满足未来 Web上企业计算的要求。论文通过分析 Web计算领域内 CORBA (comm on object request broker architecture)体系结构的优势和不足 ,以及 Java计算体系结构的优缺点 ,研究并提出满足 Web计算要求的基于 CORBA和 JavaServlet的 Web计算体系结构。采用这种新的体系结构设计并初步实现了一个原型系统。该系统是一个个人化信息查询服务系统 ,主要提供网络浏览的导航服务。与原有系统比较 ,具有良好的可移植性、互操作性和可复用性 ,并且大大提高了前端的响应处理能力 ,表明新型的体系结构能够很好地解决现有体系结构存在的一些缺陷 ,具有理论上的先进性和现实中的可行性
The existing Web computing architecture can not meet the performance and functionality requirements of enterprise computing on the Web in the future. By analyzing the advantages and disadvantages of CORBA and the advantages and disadvantages of Java computing architecture, this paper studies and proposes the Web computing architecture based on CORBA and JavaServlet to meet the requirements of Web computing. A prototype system has been designed and initially implemented with this new architecture. The system is a personalized information query service system, mainly to provide navigation services for web browsing. Compared with the original system, it has good portability, interoperability and reusability, and greatly improves the front-end response processing capability, indicating that the new architecture can well solve some existing defects in the existing architecture , With the theory of advanced and realistic feasibility
