WebSphere Commerce ( IBM WCS ) - High level steps to publish a Web Service

Steps to Publish a Controller Command as a Web Service. 

  1. Identify the business logic that you want to expose as a Web service.
  2. Identify the controller command that represents this business logic. If it is not available, then create a new controller command. You can write new commands to call a collection of existing commands.
  3. Identify the mandatory and optional parameters that this command requires.
  4. Create a WSDL description for the Web service.
  5. Register the WSDL description.
  6. Write a JSP page to compose a response.
  7. Deploy the service. This includes the deployment of related files and resources. In case of a new command, you must deploy and register it in the WebSphere Commerce command registry.
