| Re: [eclipselink-users] Hibernate ID Migration |
I would recommend you migrate this generator to a SEQUENCE or TABLE generated Id (and use a pre-allocation size). EclipseLink (and JPA) do not have a UUID generator, you could implement your own through subclassing the Sequence class (org.eclipse.persistence.sequencing) (and perhaps contribute it to EclipseLink), but I would recommend you use one of the standard id generators.
