> PostgreSQL has since version 8.3 UUID as data type nativly supported in the database. 
> The only way to get this to work in Hibernate is to add <column name="id" sql-type="uuid"/> to your mappings file (or @columnDefinition via annotations)
> and create your own custom usertype (e.g. public class UUIDUserType implements UserType, Serializable {..} ) and map this to java.util.UUID 
> worth mentioning is that java.util.UUID is only introduced in java 1.5 so there might be a backwards compatibility problem
