I have 3 tables one for OwnersSheet enity, one for Parcel entity, and one join table. And when I try this code from OwnerSheet entity:

@OneToMany(fetch=FetchType.EAGER)
@JoinTable(name="esPLParcela",
joinColumns={@JoinColumn(name="srez", referencedColumnName="srez", insertable=false, updatable=false),@JoinColumn(name="ko", referencedColumnName="ko", insertable=false, updatable=false),
@JoinColumn(name="pl", referencedColumnName="pl", insertable=false, updatable=false)},

inverseJoinColumns={@JoinColumn(name="srez", referencedColumnName="srez", insertable=false, updatable=false),@JoinColumn(name="ko", referencedColumnName="ko", insertable=false, updatable=false),
@JoinColumn(name="broj", referencedColumnName="broj", insertable=false, updatable=false),@JoinColumn(name="podbroj", referencedColumnName="podbroj", insertable=false, updatable=false)}
)
public Set<Parcel> getParcels() {
return parcels;
}

I got error:

Caused by: org.hibernate.MappingException: Repeated column in mapping for collection: com.gisdata.katastarcg.model.OwnersSheet.parcels column: ko

I can't change the column number in those tables, they are already created and filled with data.
Is there any solution to this?

Thanx, Sasha

P.S. OwnersSheet id is composed of columns srez, ko, pl and Parcel id is composed of serz, ko, broj, podbroj

Interesting thing. When I do inverse operation and write @ManyToOne and JoinTable part on the Parcel object i works without any error.

Any suggestion what could this be?

It seems to me that it is some hibernate bug. The same thing doesn't work bidirectional only one way.
