Previewing Web services
Web services can be previewed locally before being released. Unlike local previews of forms and views, which simply allow a designer to view the form or view, a local preview of a Web service has two distinct parts. First, a simple form is presented for viewing, which contains a link to the WSDL document for the web service. That link is the complete description of the service as it was designed. In addition, the web server is started on your workstation in preview mode and is able to handle SOAP requests sent to it from any other program on the same machine. Therefore development tools can be used to develop the client-side of the web service.
