Using a HexString as Id

[Alexander Malic-2]

hello

With Hibernate I was able to use a 32 character Hex-String as Id for my Entities. ( http://www.roseindia.net/hibernate/hibernateidgeneratorelement.shtml ),

How can this be done with Eclipse-Link?

regards and thanks in advance,
alexander malic

You can add your own custom sequence generator in EclipseLink through creating your own Sequence (org.eclipse.persistence.sequencing) subclass and adding it to your Session's DatabaseLogin using a SessionCustomizer.

You could also assign your id using a prePersist event, or directly from your application.

so there is no uid-generator included with eclipselink. shouldn't be too hard to write one on my own.

thanks for the help.
