[eclipselink-users] Parsing exception description...can't do it

[Laird Nelson <ljnelson@xxxxxxxxx>]

The exception description I'm getting is: 
Exception Description: The reference column name [code] mapped on the element [field donationTypeCode] does not correspond to a valid field on the mapping reference.

Is this because of a bad @ManyToOne annotation somewhere?

Thanks,
Laird
