Importing WSDL Documents
Go Up to Writing Clients for Web Services
Before you can use a Web Service, your application must define and register the invokable interfaces and types that are included in the Web Service application.
To obtain these definitions, you can import a WSDL document (or XML file) that defines the service. The WSDL importer creates a unit that defines and registers the interfaces, headers, and types you need to use.
