Hi Romain thanks
I am running some code using tomEE embedded in a main() method, using eclipse. So I've added to the run configurations->java application->my class->VM arguments -javaagent:/home/myuser/tomee/lib/openejb-javaagent.jar As suggested in (I guess) http://webspherepersistence.blogspot.com.br/2009/02/openjpa-enhancement.html But I still get an error such as INFO: Creating subclass and redefining methods for "[class xyz]". This means that your application will be less efficient than it would if you ran the OpenJPA enhancer. Exception in thread "main" javax.ejb.EJBException: The bean encountered a non-application exception; nested exception is: <openjpa-2.2.0-r422266:1244990 fatal general error> org.apache.openjpa.persistence.PersistenceException: null Am I missing something here? Your posts below talks about some system properties, is it enough to just drop them into properties.xml for tomee 1.5.2? http://rmannibucau.wordpress.com/2012/07/26/tomee-and-openejb-jpa-deploy-time-enhancement/ TIA Leo [] Leo On Wed, Sep 18, 2013 at 1:36 AM, Romain Manni-Bucau <[email protected]>wrote: > Hi > > Note: In tomee on trunk if you list your classes in persistence-unit it is > automatically done if the persistence.xml is in meta-inf/persistence.xml > Le 18 sept. 2013 04:40, "Leonardo K.
