(cross-posted to Hibernate Users as I didn't know about this forum - sorry all!)
Problem outline
The code below is an attempt to implement Created By/Date and Updated By/Date functionality in our Entity Beans.
The @PrePersist, etc annotations are copied almost exactly from the example from JSR-220 sec 3.5.3.
The issue is that the log statements at the beginning of the Pre/Post methods are never being displayed. I would expect PostLoad and PreUpdate both to be called.
Grepping the debug log output shows no reference to any of these EntityListeners at all.
Thanks in advance!
