Constructing web service in equivalent transformation programming language

Research on the Web Services has rapidly developed in recent years. A Web Service is a technology that makes the distributed applications on a network cooperate by using the standard technology of the Internet compared with the Web site. It transforms the methods and the data tendered to it from WSDL into a utilizable class, an mutual transformation of data and communication processing with the server are processed by programming done in a traditional language (C#, Java, and Perl, etc.).
