One to many table creation

I'm really new to Hibernate and this is my first app which is enterprise level. I'm stuck at one to many mapping. I did the mapping whole day but it doesn't give to correct table structure for me.

Here is the ER diagram I want to map

These are the Classes

Feed Class

@Entity
public class Feed {

@Id
@GeneratedValue(strategy=GenerationType.AUTO)
private long id;
private String name;
private long quantity;
//With getters and setters
}

Feed Order Details Class

@Entity
public class FeedOrderDetail {

@Id
@GeneratedValue(strategy=GenerationType.AUTO)
private Long id;
private double unitPrice;
private long quantity;

@OneToMany(cascade=CascadeType.MERGE)
@JoinColumn(name="feed_id")
private List<Feed> feed = new ArrayList<Feed>();

//Getters and Setters
}

after deploying app I get the following table structure

My problems are why feed_id is in Feed table? Should I add same feed every time I add a feed order detail? (it isn't a good idea)

I can achieve this by moving @OneToMany annotation and attributes to Feed table. but if I move it to Feed class how can I represent feed order details in JSP pages?

I'm using spring with this project also.
