Jay, The Oracle Business Components for Java J2EE framework provides an implementation of "Data Transfer Rowset", but does it in a way that is optionally fully updateable, too, with automatic coordination to the business tier business objects whose attribute data are shown in the rowset. Also, the developer can optionally choose to have typesafe Row "subinterfaces" generated so rather than working with a RowSet of "Row" interfaces, the developer can cast the Row to a OnLeaveEmployeesRow and then get full getter/setter method access to the data in the client, too.
