We need an integrated, robust solution for leveraging the existing applications, rapidly adapt to the unique needs and continually evolve as requirements change over time. Web Service, with loosely coupled and dynamically bound components, is the present evolution of this new category of services. lthough Web Service is very popular and in general use, which solves many problems, there are still some insufficiency. For example, it is a stateless service system, which does not record the state of each client using it and can only provide services with simpler interaction. brand-new solution, MeshObject Service Protocol (MOSP) provides another choice now. MOSP uses the concept of object-oriented, which enables users to obtain an object instance of the service provided by a peer by binding to its MOSP URL. MOSP can provide stateful services with such way. Besides, MOSP contains the concept of inheritance as well, which enables MOSP services to be reused more freely and easily, and therefore reduces the cost and time to develop applications.n this thesis, we proposed a gateway system which enables MOSP clients to call Web Service in order to promote MOSP and to make Web Service still available in MOSP environment.Chapter 1 Introduction 1.1 Background 1.2 Motivation 10.2.1 Challenges 11.3 Research Goal 14hapter 2 Related Work 15.1 Web Service 15.1.1 Extensible Markup Language (XML) 16.1.2 Simple Object Access Protocol (SOAP) 17.1.3 Web Services Description Language (WSDL) 19.1.4 UDDI (Universal Description, Discovery and Integration) 20.2 Mesh Object Service Protocol (MOSP) 21.2.1 MOSP Service Architecture 21.2.2 MOSP Object Model 22.2.3 MOSP Interface Definition Language (MIDL) 23.2.4 MOSP Messages 24.3 Interoperation between CORBA and Web Service 27.3.1 Common Object Request Broker Architecture (CORBA) 27.3.2 Gateway Systems between Web Service and CORBA 30.4 Brief Summary 36hapter 3 System Design 38.1 System Overview 38.1.1 Concept of MOSP Service 38.1.2 Design of Generic Gateway Service System 39.1.3 Design of Gateway Service 41hapter 4 System Implementation 44.1 MOSP Server, Service and Client 44.2 Gateway Factory Service 46.3 Gateway Service: onDesc() 48.4 Gateway Service: onCall() 57.5 Performance Test 60hapter 5 Conclusion 63.1 Contribution 63.2 Future Work 65.2.1 Improve limitations 65.2.2 Interoperability between MOSP and Web Service 65ibliography 68application/pdf6089415 bytesapplication/pdfen-USWeb ServiceMOSPMeshObject Service Protocol互通性WSDLSOAPGatewayhttp://ntur.lib.ntu.edu.tw/bitstream/246246/179924/1/ntu-97-R95725026-1.pdf
