Cross-platform Web services interoperability

In a real world scenario, applications have to obtain information from other programs, which may be located on the local system, on Intranet or on the Internet. Compared with traditional middleware, Web Services technology promises to solve the integration problems by providing standard-based and loosely coupled interfaces for remotely invoking functionality and accessing data. With the help of Web Services, developers can call methods running in a totally different operating system across networks. Although Web Services technology is still in the growing phase, many IT businesses have already launched their Web Services initiatives. The objective of this research is to test cross-platform Web Services interoperability and deepen the understanding of various technologies involved in Web Services. For this reason, the research focuses on two aspects: Integration with an existing Web Service, and Create Web Services implementations. For both the case studies, .NET and Java are the underlying platforms. Our results show that Web Service helps promote interoperability between systems, and SOAP cleans up interoperability problems on the web.
