I've just set things up the way you have suggested.
My PK class now has a String value referring to the country_code_1 rather than
the actual country object.
@Embeddable
| public class CountryRegionPK implements java.io.Serializable{
| .......
|
| public String getCountryCode1() {...}
|
| public void setCountryCode1(String countryCode1) {.... }
@Entity
| @Table(name = "country_region")
| public class CountryRegion implements Serializable {
| ........
| @EmbeddedId
| @AttributeOverrides({
| @AttributeOverride(name = "regionCode", column = @Column(name =
"region_code")),
| @AttributeOverride(name = "countryCode1", column =
@Column(name="country_code_1"))
| })
|
However I am still getting the error below. I'm guessing that it is due to my
Location table relationship. see bottom.
org.hibernate.AnnotationException: A Foreign key refering CountryRegion has the
wrong number of column. should be 2
| @Entity
| @Table(name="location")
| public class Location implements Serializable{
| ...........
| @ManyToOne
| @JoinColumns ( [EMAIL PROTECTED](nullable=false, name="region_code"),
@JoinColumn(nullable=false, name="country_code_1")})
| public CountryRegion getCountryRegion() {
| return countryRegion;
| }
|
