基于BPEL4WS的Web服务整合研究

业务流程执行语言（BPEL4WS）是整合Web 服务的标准，其作用是将一组现有的服务整合起来，从而定义一个新的 Web 服务。首先介绍了业务流、工作流、以及BPEL4WS在Web服务建模方面的基本概念，建立了BPEL4WS整合Web服务模型，提出了组合服务的方法和过程。最后通过实例证明了BPEL4WS服务整合的实用性。     

基于Web Services的B2B集成方案的研究与开发

论述了将Web Services技术应用于企业间信息系统的集成,分析了Web Services技术中的XML、SOAP、WSDL、UDDI等一系列协议和规范,提出了企业间集成的方案,集成时遇到的问题,通过UDDI成功无缝调用了其他企业提供的线路和天气预报查询服务,并且实现了一个调用这两个服务的商务系统。     

基于XML的B2B集成

分析了B2B的商业需求，提出利用Oracle进行B2B集成方案，并对方案的关键部件进行了详细说明。     

eXFlow: a Web Services-compliant system for supporting B2B process integration

In the B2Bi (Business to Business Integration) scenario, Business Process Management is essential for enterprises wanting to integrate internal existing processes with trading partners’ process in a manageable manner. ebXML, RosettaNet, and Web Services are among the emerging standards that will play a key role in the automation of B2Bi from the business and technology perspectives. However, the question arises of how these techniques can be engineered together to realize the B2Bi. A Web Services-compliant eXFlow solution aims to provide such an environment. This work describes this solution in detail and further examines the concepts behind this solution by using a typical B2Bi application scenario in Logistics.     

基于J2EE的统一资源描述、发现和集成(UDDI)系统

基于UDD12.0规范和J2EE架构，设计实现了UDDI统一资源描述、发现和集成系统。介绍了该系统的总体架构、关键技术及其实现,总结了系统的主要特点。     

基于XML的通用目录服务检索引擎设计与实现

目录服务在现代分布式系统中处于非常重要的地位,但是在Web Service环境下,应用程序自身的运行和调用都是通过XML形式进行描述与展现的,而传统的目录服务专有协议不支持这种形式的请求。通过适配器、转换器和DSML网关,设计了一种基于XML的通用目录服务检索引擎架构。可以使目录服务支持多种客户端,提高了目录的透明性、通用性和可达范围,适应了分布式技术由传统技术转向Web Service等转变的需要。     

Standards-based approaches to B2B workflow integration

E-business automates the overall activities of a company and allows distributed systems to communicate their information. Process automation and information sharing improve a company’s productivity and responsiveness, while Business-to-Business (B2B) workflow systems electronically aid the progress of business processes among trading partners, and also help companies to monitor and administrate their process execution. This study analyzes the technologies and standards for B2B workflow integration, and extracts a reference model for B2B workflow integration. Based on the reference model, three approaches to B2B workflow integration will be introduced here. In addition, we have developed a prototype system of one approach and have illustrated an example for B2B workflow integration. The result of our research can help business partners understand the workflow standards and the messaging technologies for B2B workflow integration, and also help them understand how to implement workflow integration systems that are appropriate to their e-business environments.     

基于语义描述的Web服务工作流动态组合研究

传统静态工作流很难适应动态的、灵活的现代业务流程。近年来Web服务技术不断发展,使得工作流中的活动以Web服务形式的实现,而且工作流本身也可以以Web服务的形式被调用,特别是语义Web技术的发展,为计算机实现自动Web服务工作流提供了可能。本文基于本体论提出了一个半结构化工作流本体模型,并在此基础上设计了基于Agent技术的Web服务工作流系统。
