Hi John,
In order to serialize some object (call it object A) that contains some
other objects (call them objects B, C, and D) then ALL the objects (A,B,C &
D) must be serializable, not just object A.
Your problem goes away when you replace the packet object with a Vector
because Vectors are serializable.
