hi, everyone:
I am not clear that whether the session object keep the same when the session migrates from one JVM to another JVM? Can session object span the multiple JVMs?
Thanks in advance!

Yes the session object can migrate across multiple JVMs. You can keep track of it's progress via the HttpSessionActvationListener.
Hope this helps,
Thomas

A session object can reside on only one JVM at a time. It can migrate accross JVMs but it cannot "span" accross JVMs, ie. it cannot exist on more than multiple JVMs at simultaneously.

hi, guys:
Thank you so much for the replies. I understand it now. What i want to do is to store a session bean reference in the session object and i did not know what would happen when the session object is migrated among the JVMs. Now i know that i can retrive the session bean reference from the session object, no matter which JVM it is on.
