You can generate the WSDL file for a message using an XML schema definition (XSD) file. When working with Mediator, you can generate a WSDL file at either of the following times:

• When you are creating a Mediator and you select the Interface Definition from WSDL template in the Create Mediator dialog, selecting Generate WSDL from Schema(s) next to the WSDL URL field opens the Create WSDL dialog.

• When you have a Mediator with no interface defined and you click Define Service next to the WSDL URL field in the Mediator Editor, selecting Generate WSDL from Schema(s) next to the WSDL URL field opens the Create WSDL dialog.

The Create WSDL dialog populates standard fields, such as the file name, directory, and namespace; and the dialog changes depending on the interface type you select. You can specify the same or different schema files for the message inputs.
