Customizing an existing configuration-based data bean mapping to return more dataIn this lesson, you customize an existing configuration-based data bean mapping to return extra requisition list data. By default, WebSphere Commerce uses REST calls for some beans and commands. Configured with mapping profiles, REST calls map REST input parameters to bean or command setter-methods, and bean/command getter-methods to REST output parameters. In some situations, customers might want to use the default REST beans or commands, but want an augmented set of response data. The configuration-based command and data bean mapping framework allows customizations where one REST mapping profile can extend another. For example, RequisitionListDataBean can be customized to return extra data and to install customizations.
