Abstract:
The basic building blocks of SOA systems are web services. The domain specific language SOAL developed by the authors has a Java and C#-like syntax for describing web service interfaces and BPEL processes. The paper introduces an extended version of the language that supports Design by Contract. From the service contract specifications software artifacts are generated that check pre- and post-conditions on the server side at runtime, applying the delegation pattern. The proposed solution provides Design by Contract for both JAX-WS and WCF technologies used in most SOA products in the industry.
