@Id application assigned

Hi,

In Hibernate it is possible to have an Id assigned by the application, is possible too with Hibernate Annotation and Hibernate EM.

In fact, I would like to assign myself the Id for an entity, because those entities are master data and I would like to the same ids accross different databases.

If I use only @Id, I got an error saying that my entity is transient (normal)

if I use

Code:

   @Id
   @GeneratedValue(generator="app-assigned")
   @GenericGenerator(name = "app-assigned", strategy = "assigned")

I got the error saying that a detach entity passed to persist (normal).

Then I use merge, but in this case I have again the error transient.

So, could someone tell what is the @Id setup I have to use to set the Id myself (in my application)?

Thanks
Dominique

do not use a @GeneratedValue if you want to assign it ;-)

Code:

@Id private Long id;
