| 摘 要： | 简要分析了基于SOAP和WSDL的WebServices动态整合的特点·根据这些特点设计了一种WebServices动态整合的体系结构和算法,基于该体系结构和算法实现了一个WebServices的动态整合平台·平台使用数据库存储的WSDL文件中的元数据和工作控制时使用的元数据,进行动态SOAP调用和服务流的控制·相对于目前已经提出的WebServices动态整合方法,例如IBM的WSFL和WSIF,它的特点是WebServices提供者可以通过Internet对服务进行在线维护,并不需要平台完成任何的维护工作,包括编程,从而使WebServices动态整合变得更为灵活和方便·

| Abstract: | The characters of the Web Services dynamic integration based on SOAP and WSDL were analyzed. A kind of architecture and algorithm was designed for Web Services dynamic integration platform. The platform employs the metadata, retrieved from WSDL files and stored in database, to invoke SOAP and control workflow. Compared with other Web Services integration resolutions, such as WSFL and WSIF of IBM, the platform makes the Web Services integration more flexible and convenient because the providers of the Web Services can maintain their services on-line through internet, the platform needs no work, and this process doesn't involve programming. |
