If a session attribute object that implements HttpSessionActivationListener needs to get notification of whether it is going to be migrated from one JVM to another JVM , is it mandatory for that Attribute Object to implement Serializable interface.
Hi, From HFSJ once a serlvet implements HttpSessionActivationListener, it's not mandatory for the class to be serialized. Serializing the class create over excess over head on performance. So, it a matter of choice and performance. With HttpSessionActivationListener, everything has been taken care of. Viola.
