can 'hbm2hbmxml' generate 'one-to-one' relationship?

I have to tables, A and B, they are of 'one-to-one' relationship, that is, the PK of B(BId), is also a FK of AId.
But when I use 'hbm2hbmxml' to generate hbm.xml, in my A.hbm.xml,
I have:

Code:

<set name="fileHeaders" inverse="true">
            <key>
                <column name="FILE_ID" not-null="true" unique="true" />
            </key>
            <one-to-many class="com.cucbc.cgo.data.FileHeader" />
        </set>

and in my A.java generated, I have:

Code:

    public Set getB() {
        return this.b;
    }
    
    public void setB(Set b) {
        this.b = b;
    }

Obviously, Hibernate gives me a one-to-many relationship, which is not what I want. I want a 'one-to-one' relationship, like in A.java, I want:

Code:

    public B getB() {
        return this.b;
    }
    
    public void setB(B b) {
        this.b = b;
    }

Can somebody tell me how to generate this using Hibernate3 Ant Tool??

Thanks a lot!

we dont detect one-to-one relationships when reverse engineering.

don't know if could do that safely anyway, but for now its not in there. you'll need to maually change the hbm.xml
