Composite Key is made up by foreign keys

[mrchit_2000]

Hi all,

I have problem finding out how to specify the member of the composite key are foreign keys pointing to primary key of other tables.
For example, If my composite key have 2 columns (A,B). I created wrapper like
public final class CompKey implements Serializable {
private int A;
private int B;

public boolean equals(Object obj) {
..............
}
public int hashcode() {
...........
}
}

Then in my class I will use
@IdClass(CompKey.class)
@Entity
public class MyClass implements Serializable{
private int A;
private int B;

}



But now I want to specify A and B as foreign keys, how do I do that? I tried using @JoinColumn and add 2 more fields to class MyClass but that gives me error saying the column names A and B are repeated.


Can someone tell me how to specify A and B as foreign key but can still use them as composite key at the same time?


Thank you very much in advance,
Lngo
