Hi
I am trying to run grails on google app engine using JDO, but I got this:
org.codehaus.groovy.runtime.InvokerInvocationException: javax.jdo.JDOFatalUserException: No meta data for Book. Perhaps you need to run the enhancer on this class? NestedThrowables: org.datanucleus.exceptions.NucleusUserException: No meta data for Book. Perhaps you need to run the enhancer on this class?
I am confused, because when I did "grails app-engine package" it looks like the DataNucleus enhancer was running.
How can I fix this?
Thanks
