No generator named "uuid" is defined in the persistence unit

You can turn the error off/down under Preferences -> Java Persistence -> JPA -> Errors/Warnings under 'Queries and Generators' by changing the error 'Generator is not defined in the persistence unit' to a warning.

This looks like a bug in the Hibernate Tools extension of Dali in Eclipse.You could report this to Hibernate Tools or maybe this is fixed in a more recent version.
