You might also want to check out the XmlOutputStream class for the 1.3 JDK, which
serializes JavaBeans in XML format. Even though the XML file is a text file, in some
cases it can be much smaller than a corresponding binary file using Java
serialization.
See http://java.sun.com/products/jfc/tsc/ for more information.
