I notice that you are using @OneToMany annotations on fields that are Long,
Integer and String???? You do not have to. The problem is that Hibernate is
now looking for another Entity class called Integer or Long or String. You
only use these association annotations on your own Entity classes.
Lets say for instance that you are intending to have many Cats in one Cart.
It would imply that the Cart class would have declared a Collection that
contains Cats. You will annotate the Collection with @OneToMany in the Cart
class.
And if you need bi-directional association then the Cat class will have
declared a Cart object too. This way, a Cat knows which Cart he is in. You
will then annotate the Cart field with @ManyToOne in the Cat class.
So in the Cat class you will have:
@ManyToOne
@JoinColumn(name="cart_id")
private cart cart;
and in the Cart class you will have
@OneToMany(mappedBy="cart")
private Collection<Cat> cats;
