JRun is trying to write the session out to disk to save memory. You have attached something to the session that is not serializable so the session is lost. If that un-serializable object is under your control, you could have the class implement Serializable and see what happens. Bill
Check your configuration. Your application should not be marked as distributable - remove the <distributable/> tag in the web.xml deployment descriptor. In a clustered environment objects must be serializable to be stored in the session because the sessions itself are serialized and transferred by the cluster server to one of a number of clients.
