How to map value-type to collection

[kwame Iwegbue]

I'm having an issue, which seems simple enough, but so far I haven't been able to figure it out. I have a Hibernate POJO Value type class (i.e not an Entity class), which I would like to compose with a few Collection objects. I do not want to make this class an Entity, in order to avoid some complex mappings, plus the class doesn't really have any need for shared references.

I'm having difficulty doing this. Does someone know how?

The value type class is itself mapped as a List, in an Entity POJO.

Here is a sample:

   
 
@Entity
@org.hibernate.annotations.Entity(dynamicInsert = true, dynamicUpdate = true)
@org.hibernate.annotations.Proxy(lazy = false)
@Table(name = "PATIENT")
public class Patient implements Serializable{
 
...
@org.hibernate.annotations.CollectionOfElements
@JoinTable(name = "PATIENT_VISIT", joinColumns = @JoinColumn(name = "PATIENT_ID"))
private List<Visit> visits = new ArrayList<Visit>();
 
...
 

@Embeddable
public class Visit implements Serializable {
 
@Column(name="CPT", nullable=false)
private List<CPT> cpt = new ArrayList<CPT>(); //here the problem. This wont work!
 
...
