I try to use it but I have the following exception:

java.lang.IllegalArgumentException: Unknown entity: java.util.UUID
        at org.hibernate.ejb.AbstractEntityManagerImpl.persist(AbstractEntityManagerImpl.java:223)
        at psqluuidtest.Main.persist(Main.java:33)
        at psqluuidtest.Main.main(Main.java:25)

The NetBeans project is attached.
The used driver is postgresql-8.4dev-700.jdbc4.

Hi,

This is very good. Can you give me some idea how to use that feature together with Hibernate JPA? Is there some special annotation or ?

Thank you very much. How can I map PostgreSQL UUID to JPA Hibernate with
annotations? Serializable or BigInteger or byte[] or java.util.UUID?

The server uuid type is already mapped to java.util.UUID in recent JDBC driver versions:
