In this thesis, we provide a overview of Web Services and ebXML. We discuss that mobile computing is the future trend of the networks. From kinds of new technologies, we choose Web Services and ebXML as the candidates of the future network trends.

　In Web Services, there are three components：SOAP, UDDI, and WSDL. SOAP is a message exchange protocol, UDDI is a repository of service profiles, and WSDL is the language that describes the contents of the services. The three components constitute a complete Web Services infrastructure. This thesis maps Web Services into Internet and explains how this infrastructure works.EbXML, founded by UN/CEFACT and OASIS, will be a new standard for business processes. It establishes common business process in order to let business partners do transactions more easily.

　This thesis combines the two technologies above mentioned to create a new business network environment. This new environment will reduce cost, increase effectiveness, and improve communications abilities. We provide a simple demo system to show the concepts and hope this thesis will be a better reference for readers.
