If you like to use build time enhancement and use Apache Maven, then I suggest to use the openjpa-maven-plugin.
You can find a sample usage of it here: https://github.com/struberg/lightweightEE/blob/master/backend-api/pom.xml I've also written a small blog post about how the different JPA strageties and enhancement work and some of the pros and cons of each approach [1]. I must admit that the deploy time enhancement got better in the meantime, but I still prefer build-time enhancement as it gives me consistent behaviour even in my tests (which you can use liberty or Apache TomEE for with either Arquillian or DeltaSpike CdiCtrl [2]) LieGrue, strub [1] http://struberg.wordpress.com/2012/01/08/jpa-enhancement-done-right/ [2] http://struberg.wordpress.com/2012/03/27/unit-testing-strategies-for-cdi-based-projects/ ----- Original Message ----- > From: Leonardo K.
