It's a requirement of Java RMI:
http://java.sun.com/j2se/1.4.2/docs/guide/rmi/faq.html#whyserial
Also, serialVersionUID can be used to implement custom class
versioning between two RMI endpoints:
http://www.oreilly.com/catalog/javarmi/chapter/ch10.html#80735
(Note that some of the built-in Java representations of some
ActionScript types and some DataServices types have to implement
Serializable because communication with ColdFusion 7 is done via RMI).

I must admit, being new to FDS/Java, can you give any examples of
specific use cases where we would need to implement Serializable?
We are using FDS with RTMP (& possibly messaging in the future). We
are persisting everything with Hibernate/MySQL.
From what I can tell we don't need it, but like I said, I am new to
this.
Thanks!

FDS 2 does not require types to implement Serializable.
The value of serialVersionUID really should be generated using the
serialver command line tool that ships with the JDK... which is a
pain to do each time you add a new class. If you don't need them
to be Serializable, then I suggest not implementing this interface.

I guess it can't hurt to have them Serializable. I'll add the
static final.

to get rid of your error add to your class:
public static final long serialVersionUID = 1L;
you only need to update the version ID with changes if you
actually store the serialized version and want make sure your not
loading and old one.

do java classes need to implement java.io.Serializabl e for use
with FDS/Hibernate?
If not is there another reason to do this? Eclipse keeps giving
me warnings whenever I implement this?
"The serializable class AddressVO does not declare a static final
serialVersionUID field of type long"
