Can you resolve this error?

[Posted via mailing list.]

I encountered this error while I was deploying my Java EE project.
I generated entity beans from mySQL and I think that raised this error but I cannot figure out what this means since I'm newbie to this tool. Can anyone help me resolve this?


Error occurred during deployment: Exception while preparing the app : Exception [EclipseLink-28018] (Eclipse Persistence Services - 2.3.2.v20111125-r10461): org.eclipse.persistence.exceptions.EntityManagerSetupException
Exception Description: Predeployment of PersistenceUnit [AffableBeanPU] failed.
Internal Exception: Exception [EclipseLink-7220] (Eclipse Persistence Services - 2.3.2.v20111125-r10461): org.eclipse.persistence.exceptions.ValidationException
Exception Description: The @JoinColumns on the annotated element [field sprint] from the entity class [class entity.TeammemberHasSprint] is incomplete. When the source entity class uses a composite primary key, a @JoinColumn must be specified for each join column using the @JoinColumns. Both the name and the referencedColumnName elements must be specified in each such @JoinColumn.. Please see server.log for more details.


Thank you.
