Re: [Hibernate] Oracle UTF8, long classnames and generated constraint names

[Gavin K. <ga...@ap...>]

Hmmmm I suppose we could add a feature like that .... would have to be an
attibute on the many-to-one, key and one-to-one elements. I won't be able to
do it for version 1.1 but perhaps you or someone else wants to have a look
at adding this for 1.2. Shouldn't be terribly hard.
