My code is now identical to the solution but still generates notserializableexception The only differences I can find: 1. The names of the arguments in the readObject and writeObject methods in the B class. Instead of "in" and "out" I use "aInputStream" and "aOutputStream". Shouldn't matter, right? 2.
