Serialization and the Serializable Fields API Serialization and the Serializable Fields API

Running the Example

Complete the following procedure to compile and run this example:

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

    javac OriginalClass.java

  2. Run the Original Class with the serialization flag:

    java OriginalClass -s

  3. Compile the Evolved Class:

    javac EvolvedClass.java

  4. Run the Evolved Class with the deserialization flag:

    java EvolvedClass -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).
