Hi lemao,
Hibernate does not add indexes when updating an existing schema (at least not afaik).
It is strange though that the index is not added when recreating the complete schema. I would try to enable hbm2ddl
logging to see more details.
See here:
http://www.elver.org/hibernate/troubleshooting.html#runtime

My experience is that if the rdb schema create statements fail that hibernate will still continue/startup. So it is easy
to miss them.

Btw, support for Teneo is given on the main EMF newsgroup which I added as cc.

gr. Martin
