Note that another solution to this is to move all Hibernate configuration data
to xwiki.properties… Since we allow property referencing in our
xwiki.properties file it would solve my need too.
It's a lot more more work though (unless we support both, looking first in
xwiki.properties for hibernate properties and fallbacking to older
hibernate.cfg.xml if not found, in which case it's a little less work but still
substantial). I'm still unsure I'm prepared to work on this now… :)
WDYT?
Thanks
