Answer 1

Check out section 2.2.5.3.3 of the Hibernate Annotations manual, which has an example suspiciously similar to yours:

In some simple situation, do don't need to associate two entities but simply create a collection of basic types or embeddable objects. Use the @ElementCollection in this case.

@Entity
public class User {

   [...]
   public String getLastname() { ...}

   @ElementCollection
   @CollectionTable(name="Nicknames", joinColumns=@JoinColumn(name="user_id"))
   @Column(name="nickname")
   public Set<String> getNicknames() { ... } 

}

Note: In older versions of Hibernate Annotations, @ElementCollection was called @CollectionOfElements.
