Re: Problem with pkclass

[Tommy Eriksson]

I was experiencing the same kind of trouble just the other day. May fault
was in implementing the PK class I had forgot to implement the equals and
the hashCode methods, hope it helps.

Example of one of my PK classes:

package knut.ejb.entity;

public class UserContactPK implements java.io.Serializable {
    public String ownerId;
    public String contactId;

    public UserContactPK(String ownerId,String contactId)  {
        this.ownerId = ownerId;
        this.contactId = contactId;
    }

    public String getOwnerId()  {
        return ownerId;
    }
    public String getContactId()  {
        return contactId;
    }

    public String toString () {
     return ownerId+":"+contactId;
    }

    public boolean equals(Object other) {
        if (other instanceof UserContactPK) {
         return ownerId.equals(((UserContactPK)other).ownerId) &&
                   contactId.equals(((UserContactPK)other).contactId);
        }
        return false;
    }

    public int hashCode() {
     return ownerId.hashCode();
    }
}
