Web Services for e-commerce, a new distributed architecture, and its goal is to address the integration and interoperability of applications in heterogeneous environment. It is built on top of open standards and technologies such as XML, SOAP, WSDL, UDDI, which, XML provides a description of the data, SOAP is responsible for the Web service calls, WSDL is responsible for the Web Services Description, UDDI is responsible to publish and discover Web services. By the definition of the service, publishing, discovery, binding, call mechanisms to achieve a loosely coupled application integration framework. Boundaries of the object system, run the Web Services-based e-commerce applications, application system across platforms, programming languages, such as public services in the form of packaging applications and for the user or other enterprise call, the formation of a Web-based information sharing and service sharing platform. This thesis is based on the Web Services technology based on Web Services technology used in the development of e-commerce. The paper first introduces the status quo of e-commerce development, analysis of the existing problems in the development of electronic commerce, business processes frequently updated collection of information between different systems on the enterprise heterogeneous platforms induction, consolidation and dissemination of difficulties. Of these issues, we need to change the design and development mode of business operation between enterprises and enterprise applications, and Web Service technology is the best means to solve these problems, it is the implementation of dynamic e-commerce provides effective technical support. Then, from the general introduction and analysis of the Web Services architecture of the structure and characteristics of the Web Services, a detailed analysis of several key technologies required for the Web Services-based e-commerce - XML, SOAP, WSDL and UDDI. Then, a B2B e-commerce as an example to analyze the Web Service solutions, and implemented using java language and associated development tools. In the instance of the application, to build a e-commerce systems integration UDDI, design and Web Query service and purchase orders as well as the client, including the service side data, access the Web Service interface, the client access to concrete realization; XML data for application in a different format, the XML Mapper to complete the mapping between different XML format document; sensitive data in the transmission of orders on the Internet (such as user name, password, or user credit card number, etc.), security issues, and the way to solve the corresponding part of the SOAP message encryption and digital signature DSA. Finally, this research project summarized, and the prospect of further work. Web Service system has good cross-platform interoperability, its development and implementation patterns and related technology solutions to promote meaningful.
