Yes, you were right. I realized there are two users were logon just before I
restarted Tomcat. As a result, the browser were trying to load the old sessions
from Tomcat.
Thanks for your help.

Are you sure you dont read in a serializef session from tomcat when
you are starting up?
If you use a new browser instance so that you really have a new
session do you still have this problem?
