Well I'm confused then. I've annotated my class with @PostLoad, @PrePersist and @PreUpdate.
The @PrePersist and @PreUpdate methods never get called, whether the methods are located in the @Entity annotated class or in a defined @EntityListeners annotated class. I've tried leaving the persistence to the DN dirty-checking persistence and also by manually re- persisting the entity using the EntityManager's persist method. The @PostLoad method is only ever called if the entity is loaded via the EntityManager's find method - if you retrieve a list of the entities via a JPA defined query then the @PostLoad method just isn't called. To the couple of people who have this working, have you got some example code/configuration you can share?
