一种基于Web服务的RIA系统集成的应用

将Flex与Web服务相结合构建RIA（Rich Internet Application,富互联网应用）系统集成,利用Web服务将应用系统中业务流程逻辑封装为标准服务,通过服务的发布与发现机制,实现企业数据资源共享;利用加密算法对传输报文数字签名和加密;利用Flex为用户提供统一的富客户端用户界面,实现高度互动性和响应性的客户端,丰富用户体验;利用模块Modules方式、导航方式、动态加载组件方式,组件重用方式等重构Flex表示层,提高系统性能,并与J2EE相整合,验证Flex与Web服务相结合构建RIA系统集成的可行性,合理性。

Application of RIA System Integration Based on Web Services

This paper designs Rich Internet Application (RIA) system integration that combines Flex and Web services. Application systems business processes are encapsulated by standard Web services. Discovery and sharing of enterprise data resources can be achieved by using the publishing and discovering mechanism of services. Transmission messages are digital signatures and encryptions by using the encryption algorithm. The unified rich client user interface and high interactivity and response of the client and rich user experience are provided by using Flex. System performance, which are improved by using modules, navigation, components of dynamic load, and components of reuse. Feasibility and rationality of the built RIA integration are verified using Flex and Web services combined with the J2EE.
