Hi Fux, Will you use DataNucleus for JDO/JPA in your data storage on the datastore or will you use something else ? (Objectify, etc...)
If you don't use JDO/JPA, that you can (even should !) remove the data enhancer from your builders. If you did not decide yet, read http://groups.google.com/group/google-appengine-java/browse_thread/thread/defc6d14445318b8/75a1e7b5bcbc1bb3#75a1e7b5bcbc1bb3 (post by Ikai Lan in this thread): should help you in your decision! regards didier On Jan 10, 4:28 pm, Fux <[email protected]> wrote: > Hi guys, I am having some troubles here, after looking at several online > resources (including IRC) I decided to post here.
