EclipseLink auto converts between most basic types. To convert to UUID or perform other type conversions you can use a Converter (see @Converter). You could also make your id the String value of the UUID to avoid the conversion. Not that EclipseLink 2.4 trunk currently has support for a UUIDGenerator.
