A software unit is a class that implements a Business Object or Business Service.  An example would be the classic Order processing example.  Some of the software units would be the Customer Object, Order object and the Order Service.  The Customer and Order Business object would contain all of the logic for accessing an Customers and Orders from persistence(e.g. database).  The Order Service would handle the logic for Customers making Orders.  All of these objects could be combined using J2EE components to make a J2EE Application.

Being self-contained means being complete and independent, i.e. a component can work for itself and has no dependences.

Functional means that it performs a function by itself, i.e. its purpose is clear and distinct.

Therefore, "self-contained functional software unit" is just a more sophisticated way of saying "a piece of software with maximum cohesion and minimum coupling", the classical definition of a software module.
