Re: Session Object Serailization

[Sean Kroah]

Sure you can make it transient, but then your not saving the state of the object in question. Your just skipping over it. The problem arises when you want to serialize and save the state of an oject that you don't have the src code to, say a JDBCConnection or any of the JAVA Collection classes that are not serializable. With a serializableAdapter you have a mechanism to make them serializable, by holding them in an Adapter class and then providing implementations of the read|writeObject methods, if I recall correctly. The article at www.javageeks.com covers it in more detail.

If that's true I doubt that every servlet engine will require that. If they do then you'll need to make all of the objects that you put into the session serializable which could be a real pain and even impossible in some cases. You can't make your jdbc connection serializable for instance.  There is an article at www.javageeks.com that shows one way to address this via a SerializableAdapter for your non serializable objects. It'd be cool if one of the tomcat guys could talk about whether, in the future,  they will require all objects in a session to be serializable. Maybe it's been discussed to death already...

If it does not, and I have a lot of sessions lying around, then will tomcat crash due to memory limitations ?
