[Xdoclet-user] Creating ValueObject with 1:1 relation

[Alexander Czernay]

I have two simple EntityBeans: ImageBean and ImageVariantBean, where 
ImageBean just holds an image's name and references to many 
ImageVariantBeans that hold the actual image-data in different variants. 
I can create perfectly well working ValueObjects for this 1:n relation 
using XDoclet. But I also have another relation between those two, 
that's called PrimaryVariant and it's a 1:1 relation.

I don't have any clue on how to model this using XDoclet. I started with 
 just adding the @ejb.value-object to my getPrimaryVariant() method, 
but this resulted in a broken ImageBeanData-object beeing created by 
XDoclet. After that, I tried to copy the whole composition settings that 
worked for the 1:n-relation between ImageBean and ImageVariantBean, but 
I can't set the type to anything else than Collection or Set.

ValueObjects for 1:1-Relations: How is this to be done?
Thanks for any help,
Alexander
