EJB3 My own SequenceGenerator Posted: Aug 13, 2009 4:15 AM

I notice @SequenceGenerator from EJB3 deals with involves ints/longs as indicated by initialValue parameter.

I need to achieve a SequenceGenerator involving: "00001", "00002", "00003" - Strings. I assume I have to create a customized SequenceGenerator? With Initial value "00000".

Would @GeneratedValue achieve this? Perhaps I can extend the Interface SequenceGenerator - but then I would need an implementation? How would that implementation injected?

Any advise would be appreciated.

ID should be 1, 2, 3, ... this means NUMBERS
Display of the ID could be "00001", "00002", "00003" ... or "one", "two", "three"....
Writting your own stuff to go around bad implementation design is not correct !
Request people to do their home work, even when painfull
