    Serialization problem of Stateful Session Bean and Seam

    Don Tsai Newbie

      I have the following problem and no idea what it means. This exception will be thrown only after the application sits still for a while without being touched by the users. I think the serialization/de-serialization happens, and somehow inbetween it has problem to proceed. By the way I am using DataModel feature of Seam with a stateful session bean. Please shed some light if you have any clue. Appreciated.
