Hey,

I have a composite key to user table.

so i have class for the composite-id - UserID (first,second)

I have class XXX like this:
1- the same pk like user
2- many to one to user.

in the many-to-one to the user i use in joincolumns like this:
@JoinColumns( { @JoinColumn(name = "first",referencedColumnName="first", @JoinColumn(name = "second",referencedColumnName="second") })

i get an exception:
repeated column for column- first
The same clumns are the PK and FK.

Can you please advice.

@Entity
public class Animal {
@EmbeddedId PK pk = new PK();
@ManyToOne
@JoinColumns( { @JoinColumn(name = "first",referencedColumnName="first"), @JoinColumn(name = "second",referencedColumnName="second") })
Owner owner;
}

@Entity
public class Owner {
@EmbeddedId PK pk = new PK();
}

public class PK implements Serializable{
public String first;
public String second;
}
