Serialization of HttpSessions

Section 7.7.2 of the 2.4 Servlet spec says that developers are not guaranteed that containers will call readObject and writeObject methods on session attributes but are guaranteed that the Serializable closure of their attributes will be preserved. Can someone please explain what this means. If I have implemented serialization on a class using readObject/writeObject am I not able to place objects of the class in the session and know that serialization will work?

I think that the specification is refering to the servet class itself, not classes you build.MeTitus

I think the wording of the spec is clear that it is talking about the serialization of session attributes.
