        I tied the way Adam suggested : no errors, but :

         

        1. If I register AuditEventListener, REVINFO table was used and all audit tables populated

        2. If I comment out AuditEventListener and don't specify any other one, audit tables were not populated.

          Yes, of course you need to specify the event listener, it's a different thing than the revision entity.

          Is the revision entity in the same jar that all other entities?

            Yes, the revision entity (CustomRevisionEntity) resides in the same jar with other regular entities (annotated as @Entity).

            Looks like AuditEventListener is not checking for annotation @RevisionEntity, but just uses REVINFO table by default.

              Is the table for CustomRevisionEntity created by Hibernate (provided that your are using hbm2ddl=update or create-drop)?

                No, I created this table manually, and it resides (revision_info and tables with suffix _aud) in the same database file with auditable tables (it's Firebird; no schemas)

                  Could you try persisting a new CustomRevisionEntity manually, to make sure that Hibernate sees that entity?

                    I will try it.

                     

                    What else I tried : I registered my listener CustomEnversListener and modified it this way

                     

                    public class CustomEnversListener implements RevisionListener, PostUpdateEventListener {

                    ...

                        public void onPostUpdate(PostUpdateEvent postUpdateEvent)

                        {

                        }

                    ...

                    }

                     

                    In this case I don't get any errors, update works fine and revision tables not populated (it's understandable why - my onPostUpdate is empty).

                    Looks like all is fine with listener itself; could be the problem persists with CustomRevisionEntity ?

                      Believe me, the EventListeners don't have anything to do here

                        Sure, I believe you !  It's just was a try ... (I saw on web one user mentioned exception will go away if we change the listener this way).

                        I just wanted to make sure the listener "listens".

                          Adam,

                           

                          I tried to persist a new CustomRevisionEntity manually, and log contains :

                           

                          .......CustomRevisionEntityHibernate.entity is null false

                          Hibernate: select gen_id( hibernate_sequence, 1 ) from RDB$DATABASE

                          Hibernate: insert into revision_info (REVTSTMP, username, REV) values (?, ?, ?)

                           

                          and table has been populated.

                           

                          But via listener :

                           

                          java.lang.ArrayStoreException: com.etranscor.domain.audit.CustomEnversListener

                                  at org.hibernate.cfg.Configuration.setListener(Configuration.java:1722)

                            Adam,

                             

                            all is fine now : the problem was in entity. Don't know how, but it was using hibernate.annotations.Entity instead of javax.persistense.Entity (my word, initially it was right; probably, after manipulating the code for listener I dropped the import statement, and the the wrong one was inserted.)

                             

                            So, for all other users having the same problem :

                             

                            in my case I registered in Spring the default listener  AuditEventListener, created CustomRevisionEntity with annotaion @RevisionEntity(CustomEnversListener.class) &  CustomEnversListener (see code in the beginning of this thread).

                            CustomRevisionEntity I registered in Spring application-context.xml under sessionFactory bean this way :

                             

                                    <property name="annotatedClasses">

                                        <list>

                                            <value>com.etranscor.domain.audit.CustomRevisionEntity</value>

                                        </list>

                                    </property>

                             

                            Please pay attention to import statement for @Entity in  CustomRevisionEntity : it must be "import javax.persistence.Entity;"

                             

                            The only problem left : how to get the real user value (inside the code and manual insert into revision_info table this code worked :

                             

                            String user= SecurityContextHolder.getContext().getAuthentication().getName();

                             

                            But in my jar that keeps only entities, it's null.

                            )

                             

                            Anyway, thank you very much for help and a great hint !
