How to get a generated ID before an object is stored?

[Dirk Manske (Service Respond)]

Hi,
 
I am using PB with DB2 and autoincrement set on. OJB is setup with the
SequenceNativeImplManager. My question is, I know that there is a way to
retrieve an ID for an object before it gets stored! I read it somewhere but
- unfortunately - cannot find the source anymore. I assume I have to use the
class Identity? Any help is appreciated. My temporary workaround is to store
the object and retrieve it back immediately (with the oid), but this seems
not to be the best way...
 
thx,
Dirk
