@SequenceGenerator

[Mark Garland]

Hi,

Probably an obvious question - just reading EJB In Action, p268 - which is discussing the @SequenceGenerator annotation.

As once declared my sequence can be used globally across the persistence unit, my question is where I should put this annotation? i.e. let's say this particular sequence is used in 2 EJB's, which one would I put it in?
If there is no real place, I would be tempted to declare it using the deployment descriptor in this case (assuming you can).

Thanks in advance,

MG

For @SequenceGenerator holds the same as for queries discussed in link.

Hi Ralph,

Thanks for the link.
The author concludes that orm.xml is the place for these declarations. Is this right?

That makes sense - it's accessible to all Entities - and it describes a mapping between a database sequence and one used in the object model.

Thanks Ralph,

MG
