> this is the enhancement strategy I have to adopt for reasons beyond the scope of this post I don't want to get this post off track, but I am interested in hearing what the problems were that you encountered with build time enhancement. Now down to my recommendation. This advise assumes that you're using the -javaagent for enhancement.? You could create a "root" persistence unit in the default location(META-INF/persistence. xml) that will be used only for enhancement. If you do not list any persistent types in the <class> list, we will enhance all Entities that are encountered at load time. I think this approach should work for you... just as long as you don't have different openjpa.DetachState settings across your persistence units. -javaagent:[path-to-openjpa-jar].jar=p=META-INF/persistence.xml#enhance-pu Thanks, Rick On Tue, Mar 29, 2011 at 4:26 AM, paulvitic <[email protected]> wrote: > Hi, > > I am using openjpa 1.2.2 with spring.
