Research On Integrated Application Based On Web Service

The booming development of the electronic commerce urge the modern business enterprise entity to change their business mode from traditional way to Internet way, therefore the business processes between the enterprises and its business partners are also gradually evolving into direct communication between the information system of each other; the continuous maturity of computer technology provides the enterprises with more and more choices when setting up their information system which results in the diversification of information system built. The environment for different systems to interact is becoming more and more complicated, and this is the bottleneck of further development of electronic commerce.The continuous increase of heterogeneous information systems makes the operability between them particularly necessary. How to dynamically integrate these heterogeneous systems and make them communicate seamlessly, realize the data exchange and share the information is the main issue which the next generation of internet structure - web service is going to resolve. Web service is based on entirely open standards and can be considered as the component development mode grounded on Internet. By providing a kind of platformindependent, language independents data format independent web access interface, it composes the business enterprise solution supporting different system platform , data format and program language under the environment of network.This issue puts great emphasis on how to adopt web service to integrate the multiply systems for operability. First it introduces the need of integrated application and the research work being done domestically and internationally; and then it introduces web service's concepts modes architecture etc.; afterwards it focuses on the main technology constituting web service including XML, SOAP, WSDL and UDDI; Finally this paper ends up with a B2B system integration demonstration and analyzes the web service solution. Microsoft Visual Studio.Net is adopted to create web service and Java is used to consume web service. This paper investigates Java's invocation of .Net web service and traces the sending and receiving of SOAP message. As Java has been born platform-independent, it can be deployed into non-Windows platform. As a result, the system developed in this paper has the good cross-platform operation ability; this verifies again that web service has the superior advantages to solve the issue of system integration.
