Running the Example

Complete the following procedure to compile and run this example:

1. From yourbasedir/objectserializationexamples/SerializationAndEvolution, compile the Original Class using JDK1.2 or higher:

   javac EvolutionExampleOriginalClass.java

2. Run the Original Class with the serialization flag:

   java EvolutionExampleOriginalClass -s

3. Compile the Evolved Class:

   javac EvolutionExampleEvolvedClass.java

4. Run the Evolved Class with the deserialization flag:

   java EvolutionExampleEvolvedClass -d

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