A business object returned by a connector to a collaboration. This business object contains response data from the connector's application or data source. Responses include the results of processes such as retrieving, changing, creating, or deleting data. When a response business object is a child of a wrapper business object, the WebSphere business integration system uses it to facilitate exchange of data to and from a URL. In this case, this business object contains response data from a URL. It is passed by a synchronous protocol handler to the appropriate collaboration. See also wrapper business object.
