When you create a WSDL file from scratch, the wizard contains three pages that you can fill out.
The Name and Location page prompts you to enter basic information about the WSDL file.
The Abstract Configuration page prompts you to define the port type, operation, and messages.
The Concrete Configuration page prompts you to define the binding, service, and port.
You do not need to complete all three pages. You can fill out the Name and Location page and then click Finish. Or you can fill out the Name and Location page and the Abstract Configuration page and then click Finish.
