mapping collections in hibernate

[John Hogan]

I have been able to map simple collections using hibernate as below:

@org.hibernate.annotations.CollectionOfElements
@JoinTable(
name = "expense_type_field_names",
joinColumns = @JoinColumn(name = "id")
)
@org.hibernate.annotations.IndexColumn(name = "position")
@Column(name = "fieldNames")
private List<String> fieldNames = new ArrayList<String>();

However, I want to change fieldnames to something like:

private Map<String, List<String> > fieldnames;

I however have no idea how I would map this to hibernate, or even if it is possible. Can someone help me?

Thanks
