Re: [Springframework-developer] Patch to support Hibernate3 - How to provide it?

[Colin S. <col...@ex...>]

Personally, I have not tried the dev. branch of Hibernate 3 yet, but if 
they have moved to a completely separate package structure, my feeling 
is that in fact mirroring the existing Hibernate 2.1 support is probably 
the only viable option. People will be using Hibernate 2.1 for quite a 
while, almost certainly for some time evern after Hibernate 3 is out, so 
we need a solution that allows Spring to work with both versions.

W/regards to how appropriate it is to add this to Spring now, it's 
probably a matter of how usable the Hibernate 3 code is. In worst case, 
this could go into the sandbox.

Regards,
Colin
