A Final Word

In this column, we continued our series on Web services. We focused here on the WebService behavior's role in hiding the complexity of SOAP message assembling and disassembling. We described the benefits of WebService and how to efficiently use it. We showed you how to call each one of its four methods, how to set each method's parameters, and what values they are returning. We explained how they interact with each other. Two of the methods, createUseOptions() and createCallOptions(), create objects that you pass to the other methods, useService() and callService().
