Alex,
I would just wait until .. I think tomorow.. Juergen is going to be
releasing Spring 1.2 RC1... which has Hibernate3 support.
OR
if you cant wait until tomorow (or soon afterwards)... just get the CVS
HEAD... its all there..
Cheers

Please respond to

Thanks everybody for your answers. My case is pretty uncommon: i am trying
to integrate the H3
support into the existing stable 1.1.5 version.
You may ask why this? I need some of the features from H3 (simple, ain't it
:-) ). So, being a week
old Spring user (in fact i haven't write a single line of code, so I would
say Spring researcher) I
thought it would be a good idea to ask the developers if my feeling was
right.
