Logger, conceptually, should not be Serializable.  

You can mark the Logger fields in those dataObjects as transient, but then
when the session reactivates the field would be null; you'll have to write
logic to handle the session activating to (re)obtain the Logger instance.
This can be done with the javax.servlet.http.HttpSessionActivationListener
interface.

    |Hi there,
    |I'm using log4j in some dataObjects that are stored in 
    |each weblogic session
    |that a user opens. When the server attempts to serialize 
    |the dataObjects in
    |the session, the following error occurs (presumably 
    |because Logger is not
    |serializable)
    |<Error> <HTTP Session> <Could not deserialize session data

    |Is there a workaround for this or do I have to take log4j out of my
    |dataObjects? Thanks
