Hello. I'm trying to map a column in a table to another column in a different table. county_id is the column in the my current object and I'm trying to match it to tinyid which is the column in the other object. What am I doing wrong?

Product Class
County county;

@OneToOne(fetch=FetchType.LAZY, cascade={CascadeType.ALL})
@JoinColumn(name="county_id", referencedColumnName="tinyid")
public County getCounty() {
return county;
}
public void setCounty(County county) {
this.county = county;
}
