Re: [eclipselink-users] Using a custom collection in EclipseLink

[James Sutherland <jamesssss@xxxxxxxxx>]

What is it a collection of?

EclipseLink allows collection implementations is you use EAGER on the
mapping.  LAZY is not supported with implementation because it requires the
interface to allow EclipseLink to use its own lazy collection
implementation.

I don't think trying to make is an Embeddable is what you want... perhaps
include your code.
