There are two basic styles of configuration for this service.
In the first style,
createRequest is implemented to call the setOperation method on the Service. This
will cause the single operation to be performed and returned as the data object in the
method. Any error status is set automatically based on the returned value of the operation.

SFTPClient. The return value of execute will be passed as the data object in the
If true, the underlying FTP connection will be disconnected after the service call. If false then it will remain open. The default value is true.

This is required unless the callback defines an execute method.
