    Error reconnecting SessionBean

    Jari Timonen Newbie

      Hello,
      My tools:
      JBoss 3.2.2
      J2SDK 1.4.2_03
      JBoss-IDE 1.2.3

      I'm having problems reconnecting my CartBean from Delegate.

      java.io.InvalidClassException: org.jboss.util.id.UID; local class incompatible: stream classdesc serialVersionUID = 4588799618105892224, local class serialVersionUID = -8093336932569424512


      This error means that i have two versions off... what?

      I don't have multiple Jboss versions.

      Here's my .packagin-file:

          Hi all,

          I get the same error trying to recreate a Stateful Session EJBObject from a cached handle.

          To re-read the object I use the following:

          byte[] bytes = new String(id).getBytes();
          java.io.ByteArrayInputStream io = new java.io.ByteArrayInputStream(bytes);
          java.io.ObjectInputStream os = new java.io.ObjectInputStream(io);

          javax.ejb.Handle handle = (javax.ejb.Handle)os.readObject();
          return handle.getEJBObject();

          Is there another way to retain the reference besides sticking the object itself into the httpSession?

          TIA,

          Graham
