when I said serialized in server.log, this is what I was referring to: 2007-10-31 16:44:38,242 DEBUG [org.jboss.ejb3.cache.simple.StatefulSessionFilePersistenceManager] Saving session state to: C:\jboss-4.2.1.GA\server\default\tmp\sessions\NoteAction-f8ghka3l-8\a1a517-i40dr2-f8ghjpkk-1-f8ghkxx0-d.ser so does this have something to do with it, part of EJB 3 SFSB lifecycle to sync with DB??
