Thanks to all that replied.
Indeed a reference to the HttpServletRequest is held in my Struts form
(session-scope). The problem went away once I added transient to the
attribute.
My concern is when the session is replicated t

CoyoteRequestFacade is the first element in the stack trace - it is not
the session stored object that is causing the NotSerializableException.
As I said in my prior posting, to resolve this issue you need to:

I know that session replication works in Tomcat 5.5.7 and it may also

Yes, you are right. For tracking all logged in users I store a reference to
every users HttpSession in his user object which is itself in the session
context.
HttpSession is org.apache.
Howdy,
You're probably putting non-Serializable objects as session
attributes...

Hi!
When I restart tomcat 4.1 I get this exeption for my webapp in the logfile.
The app works though. Am I doing something wrong concerning

Hi Andreas, I know quite enough about persistence, I
am a senior java developer myself. But the issue is
with tomcat handling persistence. Should I isolate my
imap variables and declare them transient so tomcat
will not write them to its storage?

I only add the imap session to the HttpSession. But I
do not write it to disk. What is the best way to stop
this behavior?

Obviously it does serialization. It loads a session from
persistent storage. Serialization is a means to make objects
persistent. Having written that I must confess I don't know
about sessions in Tomcat...

It looks like Tomcat is trying to serialize a session. Are you storing an
IMAPFolder object in the session?
It kacks because com.sun.mail.imap.IMAPFolder is not serializable.
