Class PackageRenamer

java.lang.Object

org.eclipse.persistence.tools.PackageRenamer

public class PackageRenamer
extends java.lang.Object

This class performs package renaming. It demonstrates the following: a) Reading the properties file to be a reference for changing the package name from your source code. b) Traverse source root directory for creating a corresponding output directory and finding the java source file(s) to be changing the package name. c) Search and replace the old TopLink package name(s) with new one(s) according to the reference. You will be able to see the logging message at the command line window where the PackageRenamer is running.
