Hi, The "mappedBy" mapping on abstract class should work and the relations need not be redefined in the concrete subclass. But a critical bug on MappedSuperclass had been found recently -- which *may be* impacting the mapping.
1. Which OpenJPA revision being used? $ java -jar /path/to/openjpa.jar shows the revision number. 2. If the used revision is prior to 952893 (dated June 8,2010), is it possible to switch to a post-952893 version and see if that resolves the issue? 3. Can you please post the relevant entity classes (JPAMesaage etc.) for further analysis? ----- Pinaki -- View this message in context: http://openjpa.208410.n2.nabble.com/OpenJPA-usage-at-Apache-James-tp5205652p5214230.html Sent from the OpenJPA Users mailing list archive at Nabble.com.
