Hello, First, thanks a lot for your answer. :)
In the past, we were using an ant build the project so also to run the JPA enhancer but for a company strategy reason we are moving to a maven build process. And when I did it, we've seen that there is a maven plugin to do the JPA enhancer. So that's why :) I just put back the default PersistenceProviderImpl and sadly, I had the same result. :( <provider>org.apache.openjpa.persistence.PersistenceProviderImpl</provider> To try to isolate the issue and, tonight, we will just replace the JPA version inside the existing project (built with ant) just to validate that has really no link with the enhancement. I will also try to upgrade openJPA version one by one to be sure from which the error appears and give additionnal data tomorrow. -- View this message in context: http://openjpa.208410.n2.nabble.com/Moving-from-OpenJPA-2-0-1-to-2-3-0-fields-not-found-tp7587168p7587176.html Sent from the OpenJPA Users mailing list archive at Nabble.com.
