Full stack trace of any exception that occurs:
org.hibernate.MappingException: Repeated column in mapping for entity: com.coginfo.kf.bean.RelazioneParametro column: codintrep (should be mapped with insert="false" update="false")

Name and version of the database you are using:
Oracle 9i

How is the correct mapping for this table? i've 2 columns that are two many-to-one with the same column codintparpdr...

read the exception and map it as such.

Only one of the associations can be used as the "master" of the column.

ok.. but whitch is the solution?
