To invoke Web services using a manually generated WebSphere® Multichannel Bank Transformation Toolkit operation, you must first create a Web services connector and then generate a Web services access operation (WSAccessOp). The Web services access operation uses the Web services connector to invoke the Web services that you want to use.
Generating a Web services access operation involves creating data mappings between the WebSphere Multichannel Bank Transformation Toolkit data model and the Web services data model. Data mapping is the process by which links are defined between two different data models so that messages can be passed between the two. Creating data mappings between the WebSphere Multichannel Bank Transformation Toolkit data model and the Web services data model enables data generated from WebSphere Multichannel Bank Transformation Toolkit operations to access the Web services data model so that the Web service can be invoked.
