Indeed, it seemd to work, thanks.
I see here http://java.sun.com/j2se/1.4.2/docs/api/java/util/Vector.html
that Vector implements the List interface, and I used Vector because it's
in the ojb documentation:
"The association is implemented by the Vector attribute allArticlesInGroup
on the ProductGroup class."
