    Serialization problem of Stateful Session Bean and Seam

    dungying
    dungying Dec 5, 2006 3:36 PM

      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.

          Hi dungying,

          I'm running through the same problem!
          I don't understand what happens with the serialization after the application stays inactive for a short time, and I cannot deal with the errors "Could not create bean ..." or "could not destroy bean...".

          Did you have any luck with it.
          I'm sure I'm missing something really important here.
          Please help. Any indication appreciated.

          Thanks,
          Elenh.
