S2HibernateJPAのサンプル作成スタート

簡単にできると思っていたが、早くもつまずいた。
joinの自動生成がうまくいかないっす。

JPAの知識足りなすぎ・・
どのアノテーションがどうなるのかがわかってない。

こんな感じじゃないのかな？
    @JoinColumn(name="deptno")
    @OneToMany(mappedBy="dept")
    private Department department;

Hibernate: 
    select
        employee0_.empno as empno1_0_,
        employee0_.deptno as deptno1_0_,
        employee0_.ename as ename1_0_,
        employee0_.job as job1_0_,
        employee0_.mgr as mgr1_0_,
        employee0_.hiredate as hiredate1_0_,
        employee0_.sal as sal1_0_,
        employee0_.comm as comm1_0_,
        employee0_.department as department1_0_,
        employee0_.tstamp as tstamp1_0_ 
    from
        emp employee0_ 
    where
        employee0_.empno=?
