Create the XML schema for a Web service

In this section you create the XML schema for a Web service.

Define a Web service

In this section, you use WebSphere Commerce Developer to define a Web service to retrieve product information. Using the XML tools, you develop an XML schema to contain the service definition. Then, using the Web service tools, you develop a WSDL document to expose the service.
