Do not post questions in the articles section.
Well the warning is telling what to do to get rid of it. Declare a final static serialVersionUID of type long and see what happens.
Eclipse likes to see it there.

The Serialization machanism (framework?) is not just about sending objects back
and forth over a wire, it also deals with *versions* of classes that are supposed to
be serialized. That same framework uses that long ID for that matter. Although
you can forget about it in your particular circumstances, formally speaking your
classes don't really fit in the Serialization framework and the compiler warns you
for it. Note that it is a warning diagnostic, not an error diagnostic.

btw, if you're using Eclipse you can either disable that warning (the bad choice)
or make Eclipse generate an ID value for you (the good choice).

kind regards,
