With the rapid development of the Internet, web service technology has been extensively used in distributed applications and is highly likely to replace other various technologies for the distributed application development. However, concerning most hard issues of the web services authentication, no proper solutions have been discovered and available for use now. Due to its dynamic and cross-domain...
Web service runtime is an important infrastructure middleware for service-based applications. It processes exchanged messages according to web service protocols. Correct implementation of web service protocols is critical for ensuring the reliability of web service runtime. In this paper, we first introduce a Service-Oriented Description Language (SODL) to precisely and concisely describe message...
With the advent of cloud computing, more services should be delivered from a cloud or datacenter to clients via Internet. Web Services has many mature specifications and has become a popular mode to support cloud application. However, the performance has been a key character to guarantee the quality of remote service in a cloud. In particular, the Simple Object Access Protocol (SOAP), being based...
The implementation of Web services specifications is the key issue of Web services container which is the infrastructure of SOC. The specifications are always depicted in natural language, which may lead to misunderstanding or ambiguity. In this situation, the implementations of the same specification by different containers will re-introduce interoperability which is supposedly addressed by Web services...
In this paper, we present a formal description of Web services container architecture based on Z notation. This description major focuses on internal behavior of a Web services container on processing a Web services request. First, we present a formal model of tailored XML which provides a unified data structure for executing Web services specifications and data transformation. Then, we present a...
