You can use javap to determine whether the entity have been enhanced. If the
entity class implements PersistenceCapable the enhancer has done its stuff.
An example from our build
$ javap org.apache.openjpa.meta.Person
Compiled from "Person.java"
public class org.apache.openjpa.meta.Person extends java.lang.Object
implements java.io.Serializable,*
org.apache.openjpa.enhance.PersistenceCapable*{
. . .
Based on Kevin's email I'd say that the app should be restarted
automatically though - but maybe this will help you make progress in the
mean time.
