    configuring persistence properties for based on release note

    k e Newbie

      i updated the /default/deploy/ejb.deployer/Meta-inf/persistence.xml file based on the release notes for 4.0.4.cr2 but it doesn't change the setting. my ejb3 app works great on 4.0.4.rc1 and shows flush=enabled but now after upgrade it won't write to the db (flush) and my server startup output shows that the flush is disabled.... how can i update this setting? is there another file i need to update?

      any ideas would be helpful thanks.

      another question? i am using stateless session beans and by default it uses REQUIRED for transaction management, so why is this affecting me, according to the release notes it is only for non-transactional db calls?

      here is the output snippet from server startup showing the flush-disabled.

          i'm using 4.0.4.GA now with no issues and i found the answer i was looking for by updating my persistence.xml properties with the correct flush modes: auto and commit.

          <persistence>
           <persistence-unit name="gwigPersistence">
           <jta-data-source>java:/MySqlDS</jta-data-source>
          
           <properties>
           <property name="hibernate.hbm2ddl.auto" value="create-drop"/>
           <property name="hibernate.transaction.flush_before_completion" value="commit"/>
           <property name="hibernate.transaction.auto_close_session" value="true"/>
           </properties>
          
           </persistence-unit>
          </persistence>
