What should I do with serializable classes?

[Sebastian Stein <se...@hpfsc.de>]

I have several classes derived either from ValidatorForm or ActionForm. Both
classes mark my derived class as serializable. I get a compiler warning
about a missing serialVersionUID.

Why are those classes serializable, because data transfered through a
network connection? How do I have to handle this warning? Should I just
define a dummy serialVersionUID?

Maybe you are using non-serializable attributes. Check out the
serializable guide in java's docs.

They are serializable because they must live in a session scope. Tomcat
will put the http sessions in persistent storage.... therefore,... you get
the picture

Hope it helps.
