Because you can put an action in HttpSession which accepts only
serializable classes - also ExecAndWait interceptor had been using
action this way, but as

I asked this question years ago and the answer I got was:
There is no reason it should be Serializable. It was originally
(mistakenly) created that way and because of compatibility it's too
late to change it now.
There is nothing magic about ActionSupport, you could always create

Hello,
Why ActionSupport is Serializable?
Who wants to serialize the action?

So properties which don't implement Serializable will just be null afterwards?
What about Lists of nonserializable classes,

hi,
i read the other day that only Objects which implement Serializable should be
put into an HttpSession.
I gues this is valid for the Session in Struts2, too?!
This seems to indicate that all the objects reachable through this object
should be serializable, too?!
That would be a problem
I wonder if making your object implement serializable will have any affect
on the Xwork object. Have you tried to see what happens?

Yes, for my own objects, i am going to implement the serializable interface,
however, the xwork class, even if i were to rewrite/replace it, i would also
have to rewrite the interceptor to use the new object ...

Hi,
I've found intriguing that the Interceptor interface extends from Serializable.
Why is that? I mean, if interceptors need to be stateless then there
is no state to save/restore.
Or is it because they are stored in application scope?

I'm studying the org.apache.struts2.showcase.ajax.AjaxTestAction class

Maybe you are using non-serializable attributes. Check out the
serializable guide
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

FormFile is an interface, so I assume it's the particular implementation

I wouldn't do it, unless you use distributed sessions. Having
serializable forms will cause tomcat to dump everything from the
session to a file, and reload it after restart. Unless you explicitely
want this (user-invisible restart, but then you need to make
EVERYTHING serializable) it
Just a quick question.
Does anybody follow any rule (personal or corporate) for when to use
"implements
serializable" on a Struts form-bean?
Kind regards

Add "implements Serializable" to the class declaration (it's an empty
