Hi, Two changes :
I had posted this question to a hibernate forum two weeks ago, before my vacation. Please ignore that line. I had found that hibernate has a dynamic-update=true option. I haven't yet found if OpenJPA has such a feature. The questions above assume that there is something like that. regards -- View this message in context: http://openjpa.208410.n2.nabble.com/dynamic-updates-tp7589912p7589913.html Sent from the OpenJPA Users mailing list archive at Nabble.com.
