1. Okay. I opted out of the dynamic weaving option; sometime later, I may try to configure static weaving.
> there are multiple packages of eclipselinks and one without the api 2. hmm, don't really understand; prior to this attempt to do dynamic weaving, my app has been running fine in TomEE 1.5.1+, and I always deploy eclipselink 2.3.2 JAR in tomee/lib, and 'never' add it to webapp webinf classes. If you're saying that tomee is shipped with eclipselink already, sorry, I didn't see it. I did recognize openejb-jpa-integration jar though.
