What is your objective? Do you want some non-JPA application to see
them in the database as Strings?
At some point you have add these Enums to the collection one at a time.
You can use an addEnum() method or an Entity listener to convert them to
Strings at that point one at a time. And a subclass of the Collection
type to getEnum() from the Collection when you fetch them back.
new MyStringEnumHashSet<MyStringEnumType>()

No, I'm talking about when the enum is in a collection.
i.e.
Private HashSet<Gender> genders=new HashSet<Gender>();
So no, either the @Enumerated helps, nor does calling name() or toString
as neither are possible.
I'm storing a Collection of enums , not a single Enum.
There seems to be no examples of this nor any documentation about the
ability to do this that I can find. The default seems to use the ordinal
value both for table generation and storage value.

Hi - This is from the OpenJPA relations example -
@Basic @Enumerated(EnumType.STRING)
private Gender gender;
public static enum Gender { MALE, FEMALE }
public void setGender(Gender gender) {
this.gender = gender;
}
See section 12.8.1.2 in the OpenJPA Overview

Ted,
If you are using Java 5, then you could use name() or toString() API on the
Enum to get the name of the enum constant in String value.

Anyone know how to store a collection of enums as Strings instead of their

i.e.
@ManyToMany
private Set<MyEnum> myEnums=new HashSet<MyEnum>();
