Using Externalization and Evolution - Java 2 SDK v1.4.2, Java 2 SDK 英文文档

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^TM 1.2 or higher:

     javac ExternExampleOriginalClass.java
   

2. Run the Original Class with the serialization flag:

     java ExternExampleOriginalClass -s
   

3. Compile the Evolved Class:

     javac ExternExampleEvolvedClass.java
   

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).
