Using Externalization and Evolution

Running the Example

Complete the following procedure to compile and run this example:

  1. From yourbasedir/objectserializationexamples/ExternalizationandEvolution, compile the Original Class using JDK™ 1.2 or higher:
  2. Run the Original Class with the serialization flag:
      java ExternExampleOriginalClass -s
  3. Compile the Evolved Class:
  4. Run the Evolved Class with the deserialization flag:
      java ExternExampleEvolvedClass -d 

This procedure tests compatibility in one direction only. To test bidirectional compatibility, perform the same procedure in the other direction (in steps 1-4, replace the original class name with the evolved class name, and vice versa).
