Research On Automatic Web Service Encapsulation And Publication

With the persistent development of network and information technique, Web Services has quickly as one of the key roles in network information integration landscape. Microsoft use "Everything is Services" generalize the Web Services' concussion to current's IT realm. So how to predigest the Web Services development process, farthest use existing platform to adapt the Web Services' change, implement handy, dynamic Web Services encapsulation, deploy and deploy process based on current technology condition has became the research hotspot.In this paper, firstly, give a simple introduction of Java platform Web Services's key technology and program model. Following, based on J2EE platform compare adopt JAX-RPC 1.1 to JSR 181 program model implement a simple Web Services, expatiate the advantage of adopting annotation program model. And then based on JAX-WS 2.0 architecture research how to implement web services use "Bottom-up pattern"(Start with Java to produce WSDL) and "Top-down pattern"(Start with WSDL to produce Java). In order to better control the services's aspect, adopt object oriented programming design, give the strategy about use the JAX-WS 2.0's handler framework to design flexible handler chain. Meanwhile, to improve the performance and reliability of long lifecycle's invoke, combine java's concurrent package to implement the asynchronous client invoke model. Finally, by particular contrast the difference and use scene, research JAX-WS 2.0 RESTful Web Services's principle, expatiate the process of development RESTful Web Services based on JAX-WS 2.0. Synthesis its feature, give the strategy about adopt use XMLHTTPRequest object to asynchronous invoke RESTful Web Services by brower.
