Hi, The annotation processing requires dependency on openjpa-all jar. Can you please explain why you declared dependencies to individual module jars but not the consolidated openjpa jar?
> I dont want to inlcude "openjpa" as a whole because i want to leave out unneeded clutter. But it seemed to be OK to include 3/4 individual openjpa*.jar -- that looks more cluttered to me. Anyway, our service file packaging will not cope with the individual jar dependencies as you have described. You need to have a single openjpa jar in your classpath To generate canonical metamodel classes using OpenJPA has two pre-requisites 1. compiler classpath must have consolidated openjpa jar 2. Compiler argument -Aopenjpa.metamodel=true must be set ----- Pinaki -- View this message in context: http://openjpa.208410.n2.nabble.com/MetaModel-creation-with-Aopenjpa-generate-true-tp6200077p6203998.html Sent from the OpenJPA Users mailing list archive at Nabble.com.
