The Abstract Configuration page of the New WSDL Document wizard prompts you to supply information about the following elements of the WSDL file: port type, operation, and message.
A port type contains one or more related operations that the web service can perform. You can create only one operation in the Abstract Configuration page. To create additional operations, you must do so from the WSDL Editor after the file is created.
Depending on the category of operation, you supply message information for the input, the output, or both the input and output. If the category of operation is Request-Response or Solicit-Response, then you can optionally supply message information for a fault.
Each message contains one or more logical parts. The Add and Remove buttons enable you to add and remove parts.
For each part, you must specify the name and the type of content. Be sure to enter a descriptive part name, such as searchInput or resultOutput. By default, the type of content is set to the built-in string type in W3C XML Schema. To change the type or to select an element instead, click the ellipsis (...) button. A dialog box enables you to select any of the built-in types in W3C XML Schema. If the project includes an XSD file, then the dialog box enables you to select an element or type from the XSD file.
When you click Next, the Concrete Configuration page appears.
