As you've found out, the session can be serialized at any time, and it may be deserialized a long time later - potentially even after the application has been restarted. At this point, the references to datasources and message resources may no longer be valid. Why are you keeping references to the datasource and message resources in the Cart now? Can you re-think your design of the Cart so that it keeps only serializable data between requests? - Peter
