Persisting a untyped Map using annotations

Hibernate version: 3.1beta3, annotations 3.1beta5
Name and version of the database you are using: MySql 4.11

I would expect there are several ways of accomplishing this, but I haven't been able to find a way to persist an untyped Map with Hibernate/annotations. What additional annotations would I need to add to this class to be able to persist it?

Code:

@Entity
public class ConfigTest {
    private Map<Serializable, Serializable> items;
    public Map<Serializable, Serializable> getItems() { return items; }
    public void setItems(Map<Serializable, Serializable> items) { this.items = items; }
    public Serializable getItem(Serializable key) { return items.get(key); }
}

I'll keep rummaging the various forums, but would appreciate a pointer.

This is somewhat quite complex to persist on any ORM unless you serialize everything in DB.
In this case you can use @Lob
