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. These may lead to the reliability problems among upper applications. Currently, formal methods is a precise mathematic way to model the specifications and verify the correctness of the properties. To solve the issues, first, we introduce an XML programming language called SODL (Service-Oriented Description Language) to describe the implementation of specifications. Then, using SODL, we describe the message processing logic according to specifications and implement a Web services container. Furthermore, the logic described in SODL can be converted to automata, by which lots of tools can be applied to verify the properties of container according to the specifications.
