Study And Implementation On Reliable Web Services Of Data Exchange Platform

The various kinds of applications which widely exist within governments and Enterprises are developed on different platforms by different technology standards. They lead to many problems including Information Island and message-sharing. This paper looks into different technologies which are used to build data-exchange platform based on web services and application integration which support different business systems. Based on extensive study on different web services, this paper chooses a solution fit for application in enterprise environment, and in accordance with this solution designs a Data-Exchange Platform based on reliable Web Service. The rationality of this platform is proved in project application.Major work of this thesis includes:1,To study the fundamentals of message middleware and transfer protocol of web services, we study and compare the different technologies which solve the reliability issues of web services, and analyze their advantages and disadvantages and their typical applications.2,Based on the study aforesaid , to present a reliable message mode based on web service and its features( that is insure message delivery, reduce message repetition and insure the sequence of message delivery), to put forward the overall structure of data-exchange platform( built on SOAP/JMS) and the design of transfer subsystem.3,Based on the design aforesaid, to partially realize the web services-based data-exchange platform whose core is SOJT middleware( SOJT is short for SOAP Over JMS Transaction). To discuss SOAP/JMS processor, assembly and realization technology of SOJT Engine, and to prove the rationality of the data-exchange platform in project application.
