基于Web服务的会话模型及其比较和应用研究

Web服务的基础规范仅支持具有简单交互协议的服务调用，不能支持需要交换一系列消息交换的复杂的电子商务交互。文中首先提出了基于Web服务的会话和会话模型的概念，试图用它们来解决双方或多方之间复杂的多步骤的长运行期的交互问题，然后从新兴的描述Web服务的会话性的各种标准归纳出两种会话模型，并对它们进行了详细的分析、应用和比较，最后给出基于会话的企业问应用集成模型，综合应用了基于这两种会话模型的标准。

Conversation Patterns of Web Services and Their Comparison and Application

The basic standards for the definition of Web Services enable the invocation of services having simple interaction protocols,but they fail to support complex E-business interactions,where the peers exchange several messages.In this paper first propose the conceptions of Web services conversation and conversational models, with the intention of using them to solve the problem of complex multi-step long-running interactions between two or more parties, and then generalize two conversational models, which are analyzed, compared and given instances in detail, from the emerging varies of technologies and standards supporting conversation with Web services, and finally present a conversation-based B2B application integration model ,which will use the emerging standards based on the proposed two conversational models.
