Hi,
I have a member which is declared in java with an interface type. This member should be embedded. I try to combine embedded with implementation-classes to let jpox know which implementation class I am using for the interface. The enhancer fails with the message that the member is declared with a type (the interface type) which is not persistence capable. Which is true as it is an interface. However because I also specify the implementation-classes extension I hoped that this would help, but it doesn't apparently.

Did I do something wrong in my metadata (see below) or is it possible for jpox to
use the implementation-classes also for embedded elements?

Thanks for any help here!

gr. Martin
