Re: [eclipselink-users] How to store an ArrayList of Enum Values?

In EclipseLink you could use a @BasicCollection for this.  You would use a
EnumTypeConverter to convert the Enum.  This mapping uses a separate table
to store the values.

You could also just serialize the collection to a binary field, but this
would not allow querying.

You could also instead change the Enum to a class and make it an Entity and
define a OneToMany or ManyToMany to it.
